| Annotation | The comparison of structural and substructural characteristics of pure zinc sulfide and biopolymer based on ZnS composite with alginate was held by scanning electron microscopy, diffraction and X-ray fluorescence spectrometry. Films and nanostructures of zinc sulfide were obtained by chemical bath deposition from an aqueous solution of zinc nitrate, sodium alginate and tiaourea at 90 °C and synthesis time of 30-120 min. It is established that growth occurs through the formation of condensate nanodots of zinc sulfide followed by merging the gaps between nanograins by alginate particles. As a result of the calculation of pole density and factor orientation it is confirmed the existence of axial texture [111] both in pure ZnS films and nanocomposites. It is shown that the lattice constants of condensates of pure ZnS vary in the range of a = 0.53266-0.54419 nm, while the lattice parameters of alginate consisting ZnS polymer nanocomposites are in the range of a = 0.53490-0.56261 nm and the inextricably dependent on time of synthesis layers. It is established that the average size of coherent scattering domains (CSD) of films of pure ZnS in the crystallographic direction [111] is weekly changed during the deposition time (L(111) = 14-29 nm). For ZnS composed of polymer nanocomposite CSD sizes vary in the range of L(111) = 21-38 nm that is larger than for pure ZnS. |
