Book Description
"Organic Light Emitting Diodes (OLEDs) based on the principle of electroluminescence, constitute a new and exciting emissive display technology for flat panel displays. In order to attain high quantum efficiency for electroluminescence, it is necessary to achieve three attributes: efficient charge injection from the electrodes at low drive voltage, good charge balance, and confinement of the injected charge carriers within the emitting layers. The purpose of this research work was to fabricate, measure and analyze OLEDs based on these fundamental principles using different cathode materials, injection layers and buffer layers in order to determine the best possible configuration. Starting from a simple bi-layered device, multilayered heterojunction OLEDs were built by employing energy band engineering. Since it was the first time that these imaging devices were being built in our Laboratory, developing tools and techniques to get reproducible OLEDs was a prerequisite to the realization of this goal. Thus, through this process, the Lab's capability was realized from the fabrication and characterization perspective, and fundamental knowledge regarding the operation of OLEDs was gained. The OLEDs fabricated were of high efficiency and brightness, and their properties match well with the published literature."--Abstract.

Book Description
"Organic light emitting devices (OLED) based on small molecule materials capable of white light emission have been fabricated and electrical and optical performance of devices was characterized. The fabricated OLEDs utilize one hole transport material, N, N'-diphenyl-N, N'-bis(3-methylphenyl)-1, 1'-biphenyl-4, 4'-diamine [TPD], and three light emitting materials including 4, 4'-bis(2, 2'-diphenylvinyl)-1, 1'-biphenyl [DPVBi], Tris-(1-phenylisoquinolinato-N) iridium (III) [Ir(piq)3], and tris-(8-hydroxyquinoline) aluminium [Alq3] to achieve the color blending close to the white light. The overall OLED configuration is in a multi-layer stacking structure. A total of 6 different OLED layer thickness configurations were implemented to investigate the effect of the layer thickness parameters. In one particular configuration, the CIE color coordinates range from (0.357,0.358) at 140.4 cd/m2 to (0.303,0.360) at 1321.7 cd/m2, which indicates adequate color stability in the medium to high luminance range. The luminance value of 1321.7 cd/m2 at the current density of 64.9 mA/cm2 and the operating voltage of 14 V indicates that the device is capable of producing a relatively high level of brightness while operating at relatively low operating voltage and low driving current density." --

Book Description
New advances offer flexible, low-cost fabrication methods for light-emitting materials, particularly in display technologies. As researchers continue to develop novel applications for these materials, feasible solutions for large-scale manufacturing are increasingly important. Organic Light-Emitting Materials and Devices covers all aspects of organic light-emitting diodes (OLEDs), focusing on the unique characteristics of electroluminescent materials, device structures, and fabrication technologies. Written by internationally recognized experts across several fields, this book first explains the multilayered structure and fundamental physics that account for OLED design. The book compiles information on the synthesis, properties, and device performance of nearly 1,000 organic small molecule- and polymer-based electroluminescent materials. It also investigates practical manufacturing techniques for OLED fabrication as well as methods used for microstructural characterization, performance measurement, and defect analysis. Later chapters discuss the patent status of the currently employed organic light-emitting materials, potential applications of OLEDs, and the challenges facing future developments from both academic and industrial perspectives. Incorporating the latest research on hundreds of light-emitting organic materials, Organic Light-Emitting Materials and Devices reflects the current understanding of molecular design in the field and reveals the most stable and efficient electroluminescent materials as well as the vast potential for future applications.
