Abstract: Chemical deposition from aqueous solutions of films of substitutional CdxPb1 –xS solid solutions with a cubic B1 structure on substrates made of monocrystalline silicon, sitall, conductive ITO coating, and a glass slide is carried out. A comparative analysis of films deposited on substrates made of various materials reveals a number of peculiarities associated with their morphology, granulometric, elemental and phase composition. To improve the quantitative assessment of the structural parameters of CdxPb1 –xS films obtained on various substrates, the profiles of diffraction reflections are proposed to be described by three- or two-phase models, taking into account the background of diffuse scattering from an amorphous material or excluding reflections from the crystalline material of the substrate. X-ray diffraction, XPS spectroscopy, and optical studies have shown that the synthesized films contain, in addition to the CdxPb1 –xS phase, impurity wide-gap compounds of Pb(OH)2, PbCO3 ∙ xPb(OH)2, and CdS.
