Charge injection and transport in single-layer organic light-emitting diodes

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 ...

Conjugated zwitterionic polyelectrolyte as the charge injection layer for high-performance polymer light-emitting diodes.

A new zwitterionic conjugated polyelectrolyte without free counterions has been used as an electron injection material in polymer light-emitting diodes. Both the efficiency and maximum brightness were considerably improved in comparison with standard Ca cathode devices. The devices showed very fast response times, indicating that the improved performance is, in addition to hole blocking, due to...

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...
