Abstract: SnS films were deposited onto the ITO glass substrates by cathodic electrodeposition from aqueous solution containing SnSO₄ and Na₂S₂O₃ with pH =2.7,Sn²⁺/S₂O₃^2-=1/5,deposition potential E=-0.72^-0.75V（vs.SCE）,and the bath temperature at 30℃ to 50℃.The result shows that the bath temperature acts some effect on the structure and properties of the films.With the bath temperature increasing,the films are compacter and the peaks of the XRD diffraction are stronger.At the same time,the light absorption range of the films shifts towards the longer wavelength with the increasing of the bath temperature.
