Description

technical field [0001] The invention relates to the technical field of preparation of nanomaterials, in particular to a preparation method of ZnS nanosheets. Background technique [0002] ZnS is a wide bandgap semiconductor material with important application value. It has excellent fluorescence effect and electroluminescence function, and shows great application prospects in the application of optics, electronics and electronic devices. For nanostructured ZnS, due to the quantum confinement effect and the dependence of light emission properties on size and morphology, it exhibits many excellent properties in the fields of electricity, magnetism, optics, mechanics and catalysis. In recent years, it has attracted the attention of researchers. At the same time, recent studies have found that wurtzite-type ZnS has superior optical properties compared with sphalerite-type ZnS. However, as a high-temperature phase of ZnS, wurtzite-type ZnS is difficult to synthesize at low temp...
