Studies on photoconductivity, photovoltaic effect and photoluminescence in chemically deposited (Cd sub(0.95)-Pb sub(0.05))S:CdCl sub(2),Dy/Y films

Results of photoconductivity (PC) and photoluminescence (PL) are presented for films of (Cd sub(0.95)-Pb sub(0.05))S:CdCl sub(2),Dy/Y prepared at 60 C and RT on glass substrates. PC is found to be enhanced in films prepared at 60 C particularly in presence of impurities. PL is found to be stronger i...

Description
Summary:Results of photoconductivity (PC) and photoluminescence (PL) are presented for films of (Cd sub(0.95)-Pb sub(0.05))S:CdCl sub(2),Dy/Y prepared at 60 C and RT on glass substrates. PC is found to be enhanced in films prepared at 60 C particularly in presence of impurities. 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 (Cd sub(0.95)-Pb sub(0.05))S:CdCl sub(2),Dy films has been found to be 65%.
