摘　　要：以醋酸锌、硫化钠为原料,乙二胺四乙酸(EDTA)为络合剂,加入分散剂聚乙二醇辛基苯基醚(OP),由正硅酸乙酯(TEOS)水解引入二氧化硅,采用共沉淀法合成水溶性ZnS纳米颗粒。通过正交实验对制备工艺条件进行研究,得出最佳工艺条件:n[(Zn(Ac)2]∶n(TEOS)=1∶0.4,OP醇溶液[V(OP)∶V(乙醇)=2∶3]用量为4 mL,n[Zn(Ac)2]∶n(EDTA)=1∶1.5,一次pH=4,反应温度为35℃,氨水用量8 mL。并采用X射线粉末衍射、荧光光谱仪对硫化锌纳米粒子性能进行表征。Surface modified ZnS nano-particles by SiO2from the hydrolysis of TEOS were prepared by co-precipitation method with Zn(Ac)2and Na2S as materials,EDTA as complexing agent,OP as dispersant.The optimal reaction condition of ZnS nano-particle synthesis was obtained through orthogonal experiment design as follows:1∶0.4 ofn(Zn(Ac)2)∶n(TEOS),4 mL of OP-C2H5OH solution [V(OP)∶V(C2H5OH) = 2∶3],1∶1.5 ofn(Zn(Ac)2)∶n(EDTA),pH 4,35℃of reaction temperature,8 mL of NH3volume.The properties of ZnS nano-particles prepared under the optimum reaction condition were also characterized by X-ray diffraction(XRD) and fluorescence spectroscopy(PL).
