Tīmeklis2010. gada 15. okt. · The ratio of [Zn]/[S] was changed from 3:1 to 1:9 by varying volumes and/or concentrations of zinc sulfate and thiourea in the deposition solution. ZnS films were obtained with the [Zn]/[S] ratio in the range of 1:1–1:6. In the cases of [Zn]/[S] ratio ≥3:1 or ≤1:9, no deposition was found.
