INVESTIGATION OF THE CRYSTALLOGRAPHIC AND OPTICAL PROPERTIES OF SULFUR-DOPED ZINC OXIDE NANOSTRUCTURES
The advancement of nanotechnology is closely tied to the development and refinement of methods for synthesizing nanostructured materials. Currently, there are more than a thousand types of methods for synthesizing nanomaterials, among which the hydrothermal method is of particular importance due to its simplicity and economic cost. At the same time, the hydrothermal method opens up significant technological possibilities for doping synthesized nanomaterials with atoms of foreign elements. Among nanostructured materials, zinc oxide (ZnO) is of particular importance due to its unique physicochemical properties. The main drawback of ZnO nanostructures is their large band gap. Therefore, the reduction of their band gap by introducing sulfur atoms into ZnO nanostructures was studied in this work
