中文摘要：
采用溶胶-凝胶法在Ti表面修饰一层纳米TiO2（nanoTiO2）膜，经X射线粉末衍射（XRD）和扫描电镜（SEM）表征，证明多孔TiO2膜的平均孔径为80nm．以该多孔膜电极为模板，借助电化学沉积的方法制备了纳米Na：SiF6（nanoNa2SiF6）．经XRD和透射电镜（TEM）测试证实该Na2SiF6为均一的白锰钒型结构，平均粒径约为20nm．初步研究了其荧光性质，发现在452．4nm和285nm处分别有强的荧光发射峰和激发峰．
英文摘要：
The nano TiO2 film was prepared by sol-gel process and characterized with X-ray diffraction （XRD） and scanning electron microscope （SEM）. It was found that the average size of pore diameter was about 80 nm for the nano TiO2 film. The Nano Na2SiF6 was synthesized by electrochemical deposition on the nanoporous film electrode and characterized with XRD and transmission electron microscope （TEM）. The result showed that the average size of nanoparticle was 20 nm for the nano Na2SiF6. The fluorescence property of nano Na2SiF6 was also studied briefly. The result indicated that the nano Na2SiF6 exhibited strong fluorescence emission at 452.4 nm and 285 nm, respectively.
