CdxTeyOz nanocomposite films were grown by the SILAR method on the CdS/ZnO surface during cyclic processing in precursor solutions followed by removal of excess reagent from the surface of the substrate by washing in hydrogen peroxide. To stabilise the surface states and saturate with oxygen, the surface was annealed in a diffusion furnace. XRD, RAMAN, and SEM analyses were used to analyse the phase composition, structural, and substructural parameters. The nanocomposite film consists of different types of oxides, namely trigonal TeO3, Monoclinic TeO4 and CdTe3O8, orthorhombic TeO2 and CdTeO3. The formation of films is explained using the Volmer–Weber growth mechanism. SEM analysis of the formed nanocomposite showed the presence of nanometer-scale globules. Partial amorphization of the heterostructure occurs due to the presence of nanometer-sized particles.
