Abstract

The invention discloses a zinc sulfide micron hollow sphere and a preparation method thereof. The hollow sphere comprises zinc sulfide, particularly, the zinc sulfide takes the shape of a micron hollow sphere with the diameter of 0.7 to 6.5 Mum, and a spherical shell is formed by nanometer rod arrays. The rod axis of the nanometer rod arrays points to the center of the micron hollow sphere. The length of the nanometer rod is 100nm to 400nm and the diameter of the rod is 50nm to 200nm; the method includes a hydro-thermal method that comprises steps as follows: step one. zinc nitrate, thiacetamide and water are mixed to obtain a precursor solution, wherein, weight proportion of zinc nitrate, thiacetamide and water is 0.4 to 0.6:0.1 to 0.3:20 to 30; step two. the precursor solution reacts under the pressure of 5 to 8 multiplied by 10Pa and the temperature of 180 DEG C to 220 DEG C for 8h to 15h to obtain precipitate products, and then the precipitate products are washed by a solvent and processed by vacuum drying to obtain the zinc sulfide micron hollow sphere. The zinc sulfide micron hollow sphere can be widely applied to the fields of medicine engineering, cosmetics, biotechnology, photochemical catalysis, photonic devices and the like, and is characterized by simple and convenient preparation method, little material consumption and no pollution.

Description

technical field

[0001] The invention relates to a hollow sphere and a preparation method thereof, in particular to a zinc sulfide micron hollow sphere and a preparation method thereof. Background technique

[0002] Zinc sulfide (ZnS) is a typical direct-bandgap, short-wavelength II-VI semiconductor material. Its band gap is wide, and the excitonic effect is obvious at room temperature. It is more suitable for making optoelectronic devices, such as high-density information reading and writing devices, full-color display devices, photoelectric conversion devices, nonlinear optical devices, underwater communication devices, biological and medical engineering devices. At the same time, ZnS has high infrared transmission performance and excellent optical and thermal properties in the infrared band, and is a good material for aircraft and laser windows. In addition, nano-ZnS has gas-sensing properties, has high sensitivity and selectivity to hydrogen sulfide, and can be used as ...
