Features of the Formation of Thin Films of Supersaturated CdxPb1–xS Solid Solutions by Chemical Bath Deposition

Resumo

Thin nanostructured films of lead sulfide-based Cd_xPb_1–xS solid solutions, strongly supersaturated with respect to the substituting component, were prepared by hydrochemical deposition from ammonia-citrate, ethylenediamine-citrate, and ethylenediamine reaction mixtures onto glass-ceramic substrates. The structure, composition, and morphology of the resulting films were examined. An interesting feature of the synthesis was revealed, a distinct correlation between the linear dimensions of the crystallites constituting the films and the cadmium sulfide content therein: the higher cadmium sulfide content, the smaller were the crystallites.
