Abstract

Multilayers of highly fluorescent nanocrystals have been investigated as emissive material in light emitting devices. Water soluble thiol-capped CdTe nanoparticles (NPs) were assembled layer-by-layer by adsorption onto oppositively charged polyelectrolytes. The arrangement of NPs in the multilayer stack was analysed through Schottky Field Emission Gun (SFEG) and Atomic Force Microscopy (AFM) techniques, while photoluminescence measurements reveal quenching effects occurring when creating inter-percolated metal-semiconductor nanostructures. Novel electroluminescent device architectures which do not involve the use of expensive indium tin oxide and are economical to manufacture were investigated. A faint luminescence at low onset voltages of 3-6V and currents of tens of mA was observed from these devices.
