Abstract

II-VI semiconductor nano particles are presently of great interest for their practical applications in many areas like photonics and optoelectronics. Modification in these properties result due to confinement of charge carriers within the nano particles. Reproducible and good quality (Zn-Cd)S: Cu are deposited on microscopic glass substrates by chemical bath deposition (CBD) technique. Characterization of these films mixed with KI/LiF/CdCl 2 is done to fabricate high efficiency electroluminescent (EL) & photoluminescent (PL) devices. The crystal structure and grain size of the particles are studied using X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). The UV-visible absorption spectra and photoluminescence (PL) spectra of various samples mixed with KI/LiF/CdCl2 are reported and discussed..
