Abstract
SnxSy films were grown by chemical spray method using aqueous solutions containing SnCl2 and SC(NH2)2 at molar ratio of Sn:S= 1:1, 1:2, 1:4 and 1:8 in the temperature interval of 200- 410 °C in air. Films were characterized by XRD, SEM, EDX and UV-VIS spectroscopy. According to XRD, films grown below 270 °C were composed of SnS as a main phase independent of Sn:S ratio in the parent solution. It has been shown that spray of 1:4 and 1:8 solutions results in thicker films with lower oxygen and chlorine content, and lower optical band gap compared to the films from 1:1 and 1:2 solutions.
