六亚甲基四胺辅助微波水热法合成γ-MnS微晶球及其光学性能
Hexamethylene Tetramine-Assisted Microwave Hydrothermal Synthesis and Optical Properties of Spherical γ-MnS Crystallites
摘要
Abstract
Spherical γ-MnS crystallites were synthesized with manganese chloride and thioacetamide as source materials and hexa- methylene tetramine (HMTA) as an additive by a microwave hydrothermal process. The influence of the HMTA amount on the phase structure and morphology of the crystallites was investigated by X-ray diffraction and field emission scanning electron microscopy, respectively. The results show that the morphology of the products changes from hexagonal columns to hexagonal flakes and self-assembled into spherical crystallites when adding the HMTA of 5 mmol. The surface of the self-assembled spheres becomes smoother, and the corresponding particle size decreases and the particle size distribution becomes narrower when the amount of HMTA increases. The UV-Visible spectrum analysis indicates that the hexagonal flakes self-assembled spherical γ-MnS crystallites have an intensive absorption peak in the ultraviolet spectrum between 300-400 nm. Also, the absorption peak becomes more and more intensive when the amount of the HMTA increases, exhibiting a red shift that may have a potential application prospect in photoelectric areas.关键词
