摘要:

利用微乳液法合成出了不同形貌的CaWO4材料,利用XRDFESEMPL谱对样品的结构、形貌和光致发光性能进行了表征。通过改变微乳液体系中表面活性剂CTAB浓度得到了近球状、花球状及纺锤体状等结构的CaWO4材料。增加反应物的浓度和反应时间,CaWO4样品的体积有进一步增大的趋势CaWO4样品的室温PL谱表明样品的发光峰位于410430 nm内,不同形貌的CaWO4样品的发光峰位置和发光强度不同。

Abstract:

CaWO4 with different morphologies were prepared with microemulsion route and characterized by XRDFESEM and PL spectra. With careful control of the surfactant CTAB concentration in the microemulsion systemCaWO4 with quasisphere-likeflower ball-like and spindle-like morphologies were obtainedrespectively. CaWO4 samples have a tendency to become larger in size with the increase in reactant concentration and reaction time. Room temperature PL spectra of the CaWO4 samples are peaked at 410430 nmthe luminous intensity and peak position are different for samples with different morphology.
