چکیده
Blue top-emitting organic light-emitting devices (TOLEDs) with highly saturated color were developed by microcavity effect. The device structure studied was glass/reflective silver/indium-tin oxide (ITO)/organic electroluminescent stack/semi-transparent cathode (calcium/silver). By changing the thicknesses of ITO and organic layers in the microcavity structure device doped with p-bis(p-N, Ndi-phenyl-aminostyryl)benzene (DSA-ph), highly saturated color with Commission Internationale de L’Eclairage chromaticity coordinates (CIEx;y) of (0.14, 0.08) was obtained. 2004 Elsevier B.V.

Influences of Device Architectures on Characteristics of Organic Light-Emitting Devices Incorporating Ambipolar Blue-Emitting Ter(9,9-diarylfluorenes)
In this article, we report the studies of various device architectures of organic lightemitting devices (OLEDs) incorporating highly efficient blue-emitting and ambipolar carriertransport ter(9,9-diarylfluorene)s, and their influences on device characteristics. The device structures investigated include single-layer devices and multilayer heterostructure devices employing the terfluorene as one...
متن کاملThin-film Encapsulation of Organic Light-Emitting Diodes Using Single and Multilayer Structures of MgF2, YF3 and ZnS
In this research, the lifetime of green organic light emitting diodes (OLEDs) is studied using four passivation layers. To encapsulate the OLEDs, MgF2, YF3, composed of alternating MgF2/ZnS and YF3/ZnS layers were grown by thermal vacuum deposition. Measurements show that the device lifetime is significantly improved by using YF3 and ZnS as passivation layers. However, diodes encapsulated by Mg...
متن کاملInvestigation of top-emitting organic light-emitting devices with highly saturated color employing metal-mirror structure
In this work, characteristics of top-emitting organic light-emitting devices (TEOLEDs) having Ag and Au as anode had been investigated. When using the same emitting materials, the performance of TEOLEDs employing Ag as anode was superior to that of the device using Au as anode. Finally, by using the appropriate dopant instead of Alq as emitter, a TEOLED with high power efficiency (8.7 lm/w with...
متن کاملStraightforward fabrication of stable white LEDs by embedding of inorganic UV-LEDs into bulk polymerized polymethyl-methacrylate doped with organic dyes
Stable white-emitting down-converted LEDs are straightforwardly prepared by bulk polymerization of an organic dye doped polymethyl-methacrylate (PMMA) shell directly on top of a highly efficient commercial blue-emitting InGaN LED. Our optimized polymerization procedure allows for extending the form factor of achievable luminescence converter (LUCO) material beyond the conventional thin film for...
