Effect of Water Concentration on the Characterization of Sprayed Cd_0.5Zn_0.5S Films

Cd_0.5Zn_0.5S film samples are prepared by a spray pyrolysis technique using aqueous solutions of CdCl₂, ZnCl₂, SC(NH₂)₂ and deionized water, which are atomized using compressed air as the carrier gas onto glass substrates with different water (H₂O) concentrations. H₂O is used as the activator. The prepared films are characterized by means of XRD and UV-VIS spectroscopy. Experimental results reveal that the structures and properties of the films are greatly affected by the H₂O content. Water in a certain range of concentrations promotes the formation of the Cd_0.5Zn_0.5S films and improves the properties of the films.
