Zustand: Sehr gut. Zustand: Sehr gut | Seiten: 309 | Sprache: Englisch | Produktart: Bücher | Although it has long been possible to make organic materials emit light, it has only recently become possible to do so at the level and with the efficiency and control necessary to make the materials a useful basis for illumination in any but the most specialized uses. The early electroluminescent panels and cells provided reasonably bright light, but required high operating voltages, produced only a narrow range of colors, and had severely limited lifetimes. Recent developments, however, make it possible to manufacture organic light-emitting devices that are thin, bright, efficient, and stable and that produce a broad range of colors.This book surveys the current status of the field. It begins with an overview of the physics and chemistry of organic light emitting devices by J. Shinar and V. Savvateev. It then turns to the design of molecular materials for high performance devices (C. Adachi and T. Tsutsui) and a discussion of chemical degradation and physical aging (K. Higginson, D.L. Thomsen, B. Yang, and F. Papadimitrakopoulos). A. Dodabalanpur describes microcavity LEDs, and Y. Shi, J. Liu, and Y. Yang discuss polymer morphology and device performance. Various aspects of devices based on polyparaphenylenes are discussed in chapters by N.C. Greenham and R.H. Friend; by Chayet, Savvateeyv, Davidoff and Neumann; and by S. Tasch, W. Graupner, and G. Leising. The book concludes with a discussion of devices based on pyridine-containing conjugated polymers by Y.Z. Wang, D. Gebler, and A.J. Epstein.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Device Architecture and Materials for Organic Light-Emitting Devices focuses on the design of new device and material concepts for organic light-emitting devices, thereby targeting high current densities and an improved control of the triplet concentration. A new light-emitting device architecture, the OLED with field-effect electron transport, is demonstrated. This device is a hybrid between a diode and a field-effect transistor. Compared to conventional OLEDs, the metallic cathode is displaced by one to several micrometers from the light-emitting zone, reducing optical absorption losses. The electrons injected by the cathode accumulate at an organic heterojunction and are transported to the light-emission zone by field-effect. High mobilities for charge carriers are achieved in this way, enabling a high current density and a reduced number of charge carriers in the device. Pulsed excitation experiments show that pulses down to 1 µs can be applied to this structure without affecting the light intensity, suggesting that pulsed excitation might be useful to reduce the accumulation of triplets in the device. The combination of all these properties makes the OLED with field-effect electron transport particularly interesting for waveguide devices and future electrically pumped lasers. In addition, triplet-emitter doped organic materials, as well as the use of triplet scavengers in conjugated polymers are investigated.…
