World Scientific Reference On Spin In Organics In 4 Volumes Book Review:

"This series summarizes the field of Organic Spintronics up to 2017. It contains four volumes dedicated to spin injection, spin transport, spin pumping, organic magnetic field effect, and molecular spintronics. The field of Organic Spintronics has accelerated and matured in the last dozen years with the realization of an organic spin-valve (in 2004) and magneto-resistance and magneto-electroluminescence in organic optoelectronic devices (2006). The book series is comprehensive in that it summarizes all aspects of Organic Spintronics to date. The first two volumes deal with spin injection, spin transport, spin manipulation and spin pumping into organic semiconductors. The main device that is thoroughly discussed here is the organic spin-valve, where spinterface states at the interface between the organic semiconductor and the ferromagnetic (FM) electrode has been the focus of many chapters. An interesting emerging subject is the role of chirality in the organic layer of the device. A relatively new method of achieving spin aligned carriers in organic semiconductors is spin pumping, where magnons in the FM substrate generate spin aligned carriers in the organic layer at the FM/organic interface. The third volume deals mainly with magnetic field effect in organic devices. Several spin-mixture processes that lead to magnetic field effect in devices and films are thoroughly discussed, such as hyperfine interaction, direct spin-orbit coupling, indirect spin-orbit coupling via [delta]g, triplet-triplet annihilation, and thermal spin alignment. The similarity between the magnetic field effect obtained in optoelectronic devices based on organic semiconductors and the novel hybrid organic-inorganic semiconductors is also a subject of intense interest. The fourth volume deals with spin in molecular films and devices. It includes thorough discussion of spin exchange interaction that leads to organic ferromagnets, as well as manifestation of various spin interactions in thin molecular films and devices."--

High Quality Perovskite Films for Efficient and Stable Light Emitting Diodes Book Review:

Metal halide perovskites have attracted significant attention for light-emitting applications, because of their excellent properties, such as high photoluminescence quantum yields (PLQYs), good charge mobility, narrow emission bandwidth, readily tunable emission spectra ranging from ultraviolet to near-infrared, and solution processability. Since the first room-temperature perovskite-based light-emitting diodes (PeLEDs) reported in 2014, tremendous efforts have been made to promote the efficiencies of PeLEDs, including theoretical simulation, materials design, and device engineering. To reach the ultimate goal of commercialization, PeLEDs with both high-efficiency and long-term operational stability are desired. Achieving high-quality perovskite emissive films is key towards this goal. Centering around the high-quality perovskite films, in this thesis, we demonstrate effective synthesis strategies for the deposition of high-quality perovskite films (including both three-dimensional and mixed-dimensional perovskites) and investigate the effects of ion migration in the perovskite films on the performance of PeLEDs. Due to the fast crystallization nature of perovskites and the low formation energy of defects, controlling the crystallization processes of these films has proved to be an effective approach for achieving high-quality perovskite films. For three-dimensional (3D) perovskite films, we have controlled the formation of these films through the assistance of molecules with the amino group. Herein, we have chosen an electron-transport molecule with two amino groups, 4,4’-diaminodiphenyl sulfone (DDS), to control the crystallization process of perovskite films (Paper 1). The resulting perovskite films consists of in-situ formed high quality perovskite nanocrystals embedded in the electron-transport molecular matrix, resulting in improved PLQYs and structural stability. PeLEDs based on these perovskite films have exhibited both high efficiency and long operational stability. In addition, we have investigated the formation of mixed-dimensional perovskite films. Efficient PeLEDs based on mixed-dimensional perovskite films were fabricated with tin dioxide (SnO2) as an electron transport layer (Paper 3). We also note that the deposition methods have a significant impact on the morphology and optical properties of prepared mixed-dimensional perovskite films (Paper 4). In addition, we provide an effective method to extend the deposition of mixed-dimensional perovskite films, replacing organic ammonium halides with amines in the perovskite precursor solutions to form organic spacer cations through the in-situ protonation process of amines (Paper 2). In spite of these efforts, the performance of PeLEDs is still far from the commercialization standard, partially limited by ion migration. In Paper 5, we discuss impacts of mobile ions in the perovskite films on the performance of PeLEDs. We find that a dynamic redistribution of mobile ions can change current density of a device, leading to EQE/hysteresis during forward and reverse voltage scan and enhanced EQE under constant driving voltages. In addition, we have found that excess mobile ions in the perovskite layer can aggravate the hysteresis and shorten the operational stability of PeLEDs. In this thesis, we also discuss the remaining key challenges in the PeLED field, including the achievement of high-performance blue, white, and lead-free PeLEDs, as well as possible strategies to address these challenges. We hope that our research findings provide insights into the basic science behind the perovskite materials, and broadly benefit other optoelectronic communities, such as perovskite solar cells, flexible electronics, and so on. Metall-halid-perovskiter har fått mycket uppmärksamhet för deras möjlighet att användas i ljusemitterande applikationer på grund utav utmärkta egenskaper så som högt fotoluminiscent kvantutbyte (PLQYs), god mobilitet, smalt emissionsband, lättjusterat emissionsspektra i intervallet ultraviolett till nära infrarött, samt för att de kan beredas med en lösningsbaserad process. Ända sedan de första perovskitbaserade ljusdioderna (PeLEDs) som verkande i rumstemperatur rapporterades 2014 har enormt arbete lagts ner på att öka effektiviteten hos PeLEDs, till exempel genom teoretiska simuleringar, materialdesign och teknisk utformning utav lysdioden. För att nå det slutgiltiga målet med kommersialisering behövs PeLEDs som har både hög effektivitet och driftstabilitet. Att uppnå högkvalitativa emitterande perovskitfilmer är nyckeln för att nå detta mål. I den här avhandlingen, vilken fokuserar på högkvalitativa perovskitfilmer, demonstrerar vi effektiva syntetiseringsstrategier för deponering utav högkvalitativa perovskitfilmer och undersöker effekterna jonmigration har på prestandan i perovskitfilmerna i PeLEDs. På grund utav den snabbkristalliserande naturen hos perovskitfilmer och den låga bildningsenergin för defekter så har kontroll utav kristallisationsprocessen av dessa filmer visat sig vara en effektiv väg för att uppnå högkvalitativa perovskitfilmer. När det gäller tredimensionella perovskitfilmer så har vi kontrollerat bildandet av dessa filmer genom assistans från molekyler med aminogrupper. Vi har valt en elektrontransporterande molekyl som har två aminogrupper, 4,4’- diaminodifenyl sulfon (DDS), för att kontrollera kristallisationsprocessen av perovskitfilmer (artikel 1). De beredda perovskitfilmerna bestod av insitu- bildade högkvalitativa perovskitnanokristaller inbäddade i en elektrontransporterande molekylär matris vilket resulterade i förbättrat fotoluminiscent-kvantutbyte och strukturell stabilitet. PeLEDs baserade på dessa perovskitfilmer har uppvisat både hög effektivitet och lång driftstabilitet. Därtill har vi undersökt bildandet av blanddimensionella perovskiter. Effektiva PeLEDs baserade på blanddimensionella perovskiter var tillverkade med tenndioxid (SnO2) som elektrontransportlager (artikel 3). Vi noterade även att val av deponeringsmetod hade signifikant effekt på IV morfologi och optiska egenskaper av de beredda blanddimensionella perovskitfilmerna (artikel 4). Därutöver tillhandahöll vi en effektiv metod för att deponera blanddimensionella perovskitfilmer genom att ersätta de vanligen använda organiska ammoniumhaliderna med aminer i prekursorlösningen för att bilda organiska distansierande katjonfilmer genom en in-situ-protoneringsprocess av aminer (artikel 2). Även om PeLEDs med högkvalitativa perovskitfilmer har visat förbättrad effektivitet och driftstabilitet så uppvisar lysdioderna fortfarande egenskaper som associeras med jonmigration. I artikel 5 diskuterar vi effekten av mobila joner i perovskitfilmer och hur de påverkar PeLEDs prestanda. Vi fann att den dynamiska omfördelningen av mobila joner i perovskitskiktet kan ändra det elektriska nettofältet i perovskitskiktet, modifiera laddningsbärarnas rekombination i perovskitskiktet och leda till ostadig strömdensitet. Dessutom har vi funnit att överskott av mobila joner i perovskitskiktet är en av de största anledningarna till den korta driftstabiliteten för PeLEDs. I denna avhandling diskuterar vi även kvarstående nyckelproblem i PeLED-fältet så som bedriften att uppnå högpresterande blå, vita och blyfria PeLEDs så väl som möjliga strategier att möta dessa utmaningar. Våra forskningsresultat ger insikter om den grundläggande vetenskapen bakom perovskitmaterialen vilka vi tror kommer vara till stort gagn för andra optoelektroniska fält, så som perovskitsolceller, flexibel elektronik och så vidare.

A New Generation of Organic Light Emitting Materials and Devices Book Review:

Since the invention of the first efficient organic light-emitting diodes (OLEDs) by C. T. Tang and S. VanSlyke, OLEDs have attracted close interest as a promising candidate for next-generation full-color displays and future solid-state lighting sources because of a number of advantages like high brightness and contrast, high luminous efficiency, fast response time, wide viewing angle, low power consumption, and light weight. The recombination of holes and electrons under electrical excitation typically generates 25% singlet excitons and 75% triplet excitons. For traditional fluorescent OLEDs, only 25% singlet excitons can be utilized to emit light, while the other 75% triplet excitons are generally wasted through nonradiative transition. By adopting noble metal phosphorescent complexes, an internal quantum efficiency (IQE) of 100% could be achieved by utilizing both the 25% singlet excitons and 75% triplet excitons. However, these phosphors usually contain nonrenewable and highcost iridium or platinum noble metals. Most recently, unity IQE has been readily achieved through noble metal-free purely organic emitters, such as thermally activated delayed fluorescence (TADF) emitters, hybridized local and charge-transfer state (HLCT) “hot exciton” emitters, binary- or ternary-mixed donor-acceptor exciplex emitters, and neutral p radical emitters, etc. In addition, the combination of conventional p-type hole-transport and n-type electron-transport materials in an appropriate device structure can also provide an uncommon efficiency. Both strategies are essential and attractive for high-performance and low-cost full-color displays and white OLED applications. This Research Topic mainly focus on this new generation of organic light-emitting materials and devices, including design, synthesis, and characterization of light-emitting organic molecules with tunable excited states, and their structural, electrical, and photophysical properties. Contributions relating to carrier transporting materials and corresponding device engineering are also included. Two mini reviews and thirteen original research articles by recognized academic experts in their respective fields are collected in this Research Topic, which will offer a broad perspective of noble metal-free organic light emitters, including conventional fluorescent emitters, TADF emitters, HLCT emitters, exciplex emitters, aggregation-induced emission (AIE) luminogens, and their corresponding devices. We believe this eBook should attract the attention of multidisciplinary researchers in the fields of materials science, organic synthesis, and electronic device engineering, especially for those engaged in OLED-related areas.

White Organic Light Emitting Diodes with Thermally Activated Delayed Fluorescence Emitters Book Review:

Recently, thermally activated delayed fluorescence (TADF) organic light-emitting diodes (OLEDs) have attracted both academic and industrial interest due to their extraordinary characteristics, such as high efficiency, low driving voltage, bright luminance, lower power consumption, and potentially long lifetime. In this chapter, various approaches to realize white OLEDs (WOLEDs) with TADF emitters have been introduced. The recent development of WOLEDs based on all TADF emitters, WOLEDs based on TADF and conventional fluorescence emitters, and WOLEDs based on TADF and phosphorescence emitters is highlighted. Particularly, the device structures, design strategies, working mechanisms, and electroluminescent processes of the representative high-performance WOLEDs with TADF emitters are reviewed. Moreover, challenges and opportunities for further enhancement of the performance of WOLEDs with TADF emitters are presented.

Circularly Polarized Luminescence of Isolated Small Organic Molecules Book Review:

This book collects all the latest advances in the leading research of the circularly polarized luminescence (CPL) of small organic molecules. Compared with that of lanthanide-based fluorophores, the research into the CPL of small organic molecules is still at the developmental stage for their relatively smaller dissymmetric factors, but has been a source of widespread attention recently. The book includes the state of the art of the discoveries in CPL organic molecules, such as helicenes, biaryls, cyclophanes, boron dipyrromethene dyes, and other chiral molecules, mostly in their isolated states, covering all possible chiral substances for future applications. This book also highlights the recent development of CPL instruments as well as time-resolved circular dichroism spectroscopy, to facilitate the further development and future design of CPL molecules.
