In recent years, the morphology control preparation of inorganic materials is of great concern, because the structure of the material to determine the performance of the material. Different morphology, the size and structure of the material having different properties. Many researchers have found that by changing the material of different morphology and size of the material showed the performance of some common materials are not available. ZnS as important of Ⅱ - Ⅵ semiconductor material, its morphology control prepared many reports study. Now there are many methods, such as solid phase method, liquid phase method and a vapor phase method, have been prepared by many different morphology ZnS materials, such as microspheres, nanoparticles, hollow microspheres, nanowires, nanorods and nanosheet and so on. In these methods, hydrothermal / solvothermal method has many advantages, such as a liquid environment, such as high temperature, high pressure, the most important of which is the hydrothermal / solvothermal There are many factors affecting the formation of the morphology, through the control of these factors, such as temperature, time, solvent, and surface active agents can be obtained a many new peculiar morphology. In this study, Solvothermal the ZnS powder material with the lamellar morphology, reaction of zinc acetate Zn (CH3COO) 2.2 H2O as a source of zinc, thiourea SC (NH2) 2 as a sulfur source, the use of water and ethylene a mixed solution of the amine as the reaction solvent, to the micelle formed by sodium dodecyl C12H25SO3Na template the ZnS powder materials obtained in the heat of a solvent having a layered structure. The tests show that the the ZnS material obtained well crystallized lamellar morphology. And explore various factors, especially solvent and surfactant formation morphology. And thus explore the formation mechanism and morphology control of layered ZnS material preparation conditions. This thesis of ZnS another study hotspot ZnS films prepared there are also studies of ZnS films attention because of the extensive application of the light emitting device, the electro-optic modulator, optical coating materials, photoconductors, and photovoltaic devices and other aspects of the laser diode, electroluminescent hot spots. Especially in thin film solar cells, solar battery buffer layer as non-cadmium, has achieved a high conversion efficiency. In this study, zinc acetate Zn (CH3COO) 2.2 H2O as a source of zinc thiourea SC (NH2) 2 as a sulfur source, ammonia and hydrazine hydrate as a complexing agent, prepared a large area on the glass substrate by hydrothermal method, uniform the nanostructure network like ZnS films. The tests show that the resulting film is smooth, and nano-network-like structure. Paper also complexing agent film, the mechanism of action of the complexing agent in the hydrothermal film.
