【摘要】 在溶液的pH=2.7,离子浓度比Sn2+/S2O32-=1/5,沉积电位为-0.72~-0.75V(vs.SCE)的条件下,控制溶液的温度在30~50℃之间变化,用阴极恒电位电沉积法在ITO导电玻璃基片上沉积SnS薄膜。通过对薄膜的结构和光学性能研究,结果表明:溶液的温度越高,制备出的SnS薄膜更加致密,均匀,薄膜的衍射峰也越来越明显;同时SnS薄膜对光的吸收范围也向长波方向拓宽。更多还原

【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.更多还原
