Synthesis, electrical properties, and structural features of copper-containing chalcogenide films produced by the chemical deposition method

Multicomponent copper-containing CuI-AsI₃-As₂Se₃ and CuI-Sb₃I-As₂Se₃ chalcogenide films were produced by chemical deposition from solutions of chalcogenide glasses in n-butylamine and their electrical conductivity was studied. It was shown that the electrical properties of chalcogenide glasses and films based on these glasses have the same values within experimental error. It was found sing Mossbauer spectroscopy that antimony atoms are in the Sb(III) state in the environment of three selenium atoms, and copper ions in the Cu(I) state and are surrounded by iodine atoms. The chalcogenide films can be used to fabricate ion-selective electrodes sensitive to copper cations.
