| Abstract: | Photoconductivity (PC) and photoluminescence (PL) emission spectra of different CdS-Se films doped with lanthanides Ho/ Nd, prepared by chemical bath deposition (CBD) method have been studied. The Scanning electron microscope (SEM), X-ray diffraction (XRD) and optical absorption spectral studies have been used for characterization. The PC studies show an enhancement in the photocurrent with the doping of flux and lanthanides. The PL emission spectra of undoped films show excitonic as well as donor-acceptor transitions, where as that of different doped films exhibit visible transitions between different energy levels of the impurities Ho and Nd. |
