A light-emitting device based on a CdTe nanocrystal/polyaniline composite

Abstract

CdTe nanocrystal/polyaniline composite films as well as films of closely packed CdTe nanocrystals were used to fabricate light-emitting devices with low turn-on voltages [∽2.5 V for a device with a Mg cathode and an indium tin oxide (ITO) anode]. In principle, the emitted colour is tunable from green to red, depending on the size of the nanocrystals. The use of the particle loaded polyaniline film as the light-emitting layer results in a considerable enhancement of the quantum efficiency in comparison with the polymer-free device with closely packed CdTe nanocrystals. The light-emitting devices are found to work more efficiently in a pulsed mode than under continuous operation.
