Preparation of ZnS:Mn nano-crystalline particles and investigasion of the application of the particle to PVCz EL devices

Abstract

We have investigated PVCz multi-layered electroluminescence(EL)devices doped with ZnS based nano-crystalline particles. The particle size of prepared nano-crystal is varied from 2 nm to 5 nm. We have observed electroluminescent emission from the nano-crystalline particle doped PVCz polymer EL devices for ZnS:Mn and Zn_x Mg_<1-x> S:Mn nano-crystals. We have described and discussed current-voltage and luminance-voltage characteristics together with EL spectrum for PVCz EL devices doped with nano-crystalline particles. Preparation and characterization of nano-particles are also described and discussed.
