Abstract. Thin films of Cd 1−x Zn x S (CZS) were prepared by a novel spin coating/melt method from cadmium ethylxanthato [Cd(C 2 H 5 OCS 2) 2] and zinc ethylxanthato [Zn(C 2 H 5 OCS 2) 2] in x ratios of 0–0.15 and of 1. A solution of the precursor(s) in THF was spin coated onto a glass substrate and then heated at 250 °C for 1 h under N 2.The thickness of the film formed can be controlled ...
