Device Structures and Materials for Organic Light Emitting Diodes
Organic light emitting devices (OLEDs) are promising candidates for light-weight color flat panel displays. Different device structures with emission in the blue, green, and red spectral region are discussed with respect to their optical and electrical characteristics. Blue OLEDs based on OXD-8 as emitter molecule show quantum efficiencies of 0.9 % (2.2 cd/A, 0.6 lm/W), green emitting devices b...
متن کاملEfficient molecular organic light-emitting diodes based on silole derivatives
We report the performance of molecular organic light-emitting diodes (MOLEDs) using silole derivatives as emissive and electron transport materials. Two siloles, namely 2,5-di-(3biphenyl)-1,1-dimethyl-3,4-diphenylsilacyclopentadiene (PPSPP) and 1,2-bis(1-methyl-2,3,4,5,tetraphenylsilacyclopentadienyl)ethane (2PSP), with high PL quantum yields of 94% and 85%, respectively, were used as emissive ...
متن کاملOrganic Light Emitting Diodes: Device Physics and Effect of Ambience on Performance Parameters
Research in Organic Light Emitting Diode (OLED) displays has been attaining greater momentum for the last two decades obviously due to their capacity to form flexible (J. H. Burroughes et al, 1990) multi color displays. Their potential advantages include easy processing, robustness and inexpensive foundry (G.Yu & A.J.Heeger, 1997) compared to inorganic counterparts. In fact, this new comer in d...
متن کاملOrganic Light-emitting Diodes and Organic Light-emitting Electrochemical Cells Based on Silole-Fluorene Derivatives
Silole groups are known to present a high electron affinity. Initially, copolymerization of siloles with fluorene was aimed at improving electron injection into the polymer layer and so improving the electroluminescent properties of Organic Light Emitting Diodes (OLED’s) made from fluorene. But it also provides the ability to turn the light emission colour to the green part of the spectrum and ...
متن کاملNovel host materials for single-component white organic light-emitting diodes based on 9-naphthylanthracene derivatives†
A series of 9-naphthylanthracene based dimers and trimers were synthesized and characterized. TGA studies reveal that they are all thermally stable with decomposition temperatures well above 500 C. Upon optical excitation, all of these dimers and trimers show intense blue emission in common organic solvents, accompanied by a new peak at long wavelength in the solid state. They exhibit nanosecon...
