Abstract
Results of photoconductivity (PC) and photoluminescence (PL) are presented for films of (Cd0.95-Pb0.05)S:CdCl2,Dy/Y prepared at 60 � Ca nd RT on glass substrates. PC is found to be enhanced in films prepared at 60 � C particularly in presence of impuri- ties. PL is found to be stronger in films prepared at RT. While films prepared in presence of Dy show one peak in green yellow region, those prepared in presence of Y show two peaks one in blue and other in green yellow regions. Results of SEM, XRD, and optical absorption spectra, which have been used to characterize the materials, are presented. Photovoltaic efficiency in (Cd0.95-Pb0.05)S:CdCl2,Dy films has been found to be ~5%.
