Facile synthesis of SnS microrods films prepared by electrochemical Deposition

摘要

Despite plenty of reports on the preparation of SnS films, it remains challenging to grow SnS microrods films. In this paper, we describe a facile synthesis of the SnS microrods films, utilizing constant potential cathodic electro-deposition method, as well as the investigation of its structure and optical properties. The synthesis involves a mixture of stannous sulfate, EDTA and sodium thiosulfat. Preliminary studies on the growth mechanism indicate that SnS films are preferentially oriented along the (101) plane, which is quite different from the previous report that oriented along the (111) plane. Raman spectra indicate that the microrods films have a high purity.
