AgGaS2 thin films have been prepared on quartz substrates by means of XeCl excimer laser deposition from a mixture target of Ag2S and Ga2S3. Measurements of X-ray diffraction, Raman scattering, transmission and photoluminescence spectra show that the deposited films were chalcopyrite-type, polycrystalline AgGaS2 compound highly oriented in the [112] direction.
