ZnS纳米复合材料的制备及性质

PREPARATION AND CHARACTERIZATION OF COMPOSITE MATERIAL OF ZnS NANOCRYSTALS

以硫代乙酰胺、硝酸锌、桑色素为原料用液相沉淀法制备了ZnS纳米晶 /桑色素复合材料 .样品的测试结果表明 :ZnS表面原子能与桑色素形成较牢固的化学键 ,生成稳定的复合材料 .复合后ZnS纳米晶的稳定性和发光性能发生了改变 .这为进一步研究和开发ZnS纳米复合材料提供了实验依据 .

ZnS/morrin composite material was prepared by sol ut ion deposition method from thioacetamide、zinc nitrate and morrin.The experiment al results show that there is strong bonds between the morrin molecules and surf ace Zn atoms of ZnS nanocrystals,thus stable composite material formed.Both the stability and photoluminescent properties of the ZnS nanocrystals changed after the composite reaction with morrin.
