ZnS：Mn^2＋,Eu^3＋发光纳米材料的油-水界面法合成

Synthesis of ZnS：Mn^2＋,Eu^3＋Luminescent Nano-materials by Oil-water Interface Method

以硬脂酸锌为Zn源、硫化钠为S源,首次采用油水界面法制备出单分散于环己烷和甲苯的ZnS纳米材料,探索有机溶剂、锌源和油酸浓度等对紫外吸收影响的同时,以ZnS为基质,掺杂Mn^2＋和Eu^3＋制得ZnS：Mn^2＋,Eu^3＋发光纳米材料,采用高分辨率透射电子显微镜（HRTEM）、X射线粉末衍射仪（XRD）、紫外可见（UV-VIS）和荧光分光光度计（PL）对产物进行了表征,紫外和HRTEM测试结果均表明,产物为单分散性,平均粒径为4.3 nn;荧光测试表明,产物所发荧光较强,肉眼可观测到明显的橙黄色（585 nm）和橙红色（616 nm）发光;XRD结果显示。

The stable ZnS nano materials dispersed in cyclohexane and toluene were firstly obtained by the oil-water interface method using zinc stearate and sodium sulfide as Zn-source and S-source,respectively.And effects of the organic solvent.Zinc sources,and concentration of oleic acid were also investigated.Meanwhile.ZnS：Mn^2＋,Eu^3＋ luminescent nano-materials were obtained by doping Mn^2＋ and Eu^3＋ into the zinc sulfide substrate.The products were characterized by transmission electron microscopy（TEM）,X-ray diffraction（XRD）,ultraviolet spectroscopy（UV-vis） and photoluminescence spectroscopy（PL）.UV and HRTEM results showed that the nano—materials were nearly monodispersed and the average diameter was 4.3 nm.And the fluorescence of orange—yellow（585 nm） and orange—red（616 nm） was found by naked eves and monitored by PL.XRD image indicated that the structure of as-prepared ZnS and ZnS：Mn^2＋、Eu^3＋ nano—materials was cubic sphalerite.
