Abstract
Lead sulfide films doped with cadmium and iodine ions were obtained by chemical bath deposition from the reaction mixture with thiourea that have thickness of up to 300 nm. An increase in cadmium iodide in the reactor from 5∙10-5 to 5∙10-3 mol/l is accompanied by a decrease in the period of the B1 cubic crystal lattice (space group ) from 0.59368 to 0.59355 nm, due to the replacement of Pb2+ ions in the PbS crystal lattice by a smaller size of ion Cd2+. The cadmium content in the synthesized layers varied from 0.4 to 2.8 at.% with a constant iodine concentration of 1.7–1.9 at.%. An electron microscopic study of the structure showed a decrease in the average crystallite size from 260 nm to 80 nm.
