Download or read book High Efficiency Blue Phosphorescent Organic Light Emitting Diodes written by Neetu Chopra and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Organic light emitting diodes are touted as a promising candidate for solid state lighting. Keeping in mind the energy situation world is facing today, it is imperative to have a low cost, large area, low energy consumption lighting alternative and that's where organic light emitting diodes become very important. Also, OLEDs are very attractive from the standpoint of full color display application because of desirable properties such as wide viewing angle and easy fabrication. For both of these applications, white light is desirable which can be obtained from the combination of basic color components i.e. RGB. Phosphorescent organic materials are inherently four times more efficient compared to fluorescent materials. Using these phosphorescent materials, very high efficiencies have been achieved for red and green OLEDs. However, blue emitting phosphorescent devices were still lagging behind in terms of device efficiency until very recently. The focus of this work has been to remove this weak link in development of high efficiency white OLEDs by studying the materials and device properties. For understanding factors impacting the device performance, effects of material properties such as triplet energy and mobility on the device performance of blue phosphorescent organic light emitting diodes (PHOLEDs) were investigated.

Download or read book A New Generation of Organic Light Emitting Materials and Devices written by Shi-Jian Su and published by Frontiers Media SA. This book was released on 2019-11-27 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
