Organic light-emitting diodes based on sodium chloride buffer layer

Investigation on internal electric field distribution of organic light-emitting diodes (OLEDs) with Eu2O3 buffer layer

Organic 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 ...

Charge carrier mobility of mixed-layer organic light-emitting diodes

The authors report the investigation of the charge transport behaviors in mixed thin films of N ,N -diphenyl-N ,N -bis 1-napthyl -1 ,1 -biphenyl-4 ,4 -diamine and tris 8-hydroxyquinoline aluminum. The extracted electron and hole drift mobility were found to be sensitive to the compositional fraction and interpreted by energy levels, charge mobilities of neat compounds, and microscopic networks ...

Carrier modulation layer-enhanced organic light-emitting diodes.

Organic light-emitting diode (OLED)-based display products have already emerged in the market and their efficiencies and lifetimes are sound at the comparatively low required luminance. To realize OLED for lighting application sooner, higher light quality and better power efficiency at elevated luminance are still demanded. This review reveals the advantages of incorporating a nano-scale carrie...

Efficient 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 ...
