Silver sulphide films were prepared by chemical bath deposition (CBD) Method in room temperature. The semiconducting Silver Sulphide thin films were deposited on the glass slide in bath containing aqueous solution of silver nitrate, thiourea, EDTA, ammonia and Pr Rare Earth. Silver nitrate used for silver ion, thiourea for sulphur ion, EDTA is the complexing agent and ammonia used for maintaining the pH. SEM micrograph indicate the presence of Flower type structure along with presence of micro particle. Photoluminescence study show the emission and absorption peak of doped and undoped film. Photocurrent, Dark current, excitation behavior and photoconductivity rise and decay studies has been done. In the Excitation spectra photocurrent exist in the ultra violet region. Quite good photosensitivity is observed in silver sulfide thin films.
