Abstract—PbSe and In films with surface areas of 3 3 mm² and thicknesses of 1–1.5 m were consecutively
deposited on substrates made of glass of S-29 grade using the vacuum deposition method. The films were oxi-
dized in the dry air atmosphere at a temperature of 550C. The possibility of forming whisker nanocrystals (1–
x)In₂O₃ · xSeO₂ on glass substrates was demonstrated. The results of X-ray microanalysis demonstrated the
presence of not only lead and indium selenide, but also (1 – x)In₂O₃ · xSeO₂, PbSeO₃, PbO and SeO₂ on the
surfaces of the films under study.
