Abstract

The (Ag2S):cdcl2,Pr,Ho thin films have been prepared by chemically bath deposition technique at room temperture. The outcomes of Scanning electron microscopy (SEM), photoluminescence (PL) emission spectra and photoconductivity (PC) rise and decay studies are reported in the prepared samples .The SEM Micrograph show void ball-type structures and its group’s together forms layer, some flower type structure are also observed in doped films. The optical absorption spectra show the presence of Pr, Ho in the lattice. In the Photoconductivity rise and decay studies the effect of flux, impurities and photo to dark current ratio Ipc/Idc is observed. The value of Ipc/Idc ~104 is obtained for the host and impurity doped films. In the photoluminescence (PL) study we have observed Excitation and Emission peaks are related to transitions between excitonic levels and levels due to Pr, Ho.
