Low Temperature Route For Synthesis Of Silver Selenide Thin Films And Their Properties: Annealing Effect

M.B.Dongare and S.J.Pawar

Silver Selenide (Ag2Se) thin film has been electrodeposited at room temperature from an aqueous acidic bath containing silver nitrate (AgNO3) and selenium dioxide (SeO2) as precursor salt with ethylene di-amine tetraacetic acid (EDTA) as a complexing agent. The electrodeposition of Ag2Se thin film was carried out by varying the time of deposition. The influences of preparative parameters on growth of Ag2Se thin film have been studied. This electrodeposited film has been characterized by X-ray diffraction (XRD) for their structural studies. Surface morphological study of Ag2Se thin film was carried out by Scanning Electron Microscope (SEM). Band gap of Ag2Se thin film was calculated by using UV-Visible spectrophotometer. ï›™ 2006 Trade Science Inc. - INDIA
