The Study on Luminescence Properties of NaLa_9(SiO_4)_6O_2:Dy^(3+)

采用高温固相法合成了荧光粉基质NaLa_9(SiO_4)_6O_2,制备NaLa_(9(1-x))(SiO_4)_6O_2:9xDy^(3+)系列白色荧光粉,并通过X射线衍射仪、荧光光谱仪等仪器对样品的晶体结构和发光性能进行了表征。X射线衍射结果表明,本次试验成功制备了NaLa_(9(1-x))(SiO_4)_6O_2:9xDy^(3+)荧光粉;荧光光谱表明,该荧光粉的最佳掺杂摩尔分数x=0.03。

A series of rare-earth luminescent materials NaLa9（SiO4）6O2：Dy^3＋ phosphors were synthesized by high temperature solid state reaction method. The structure and luminescent properties of these phosphors were studied by X-ray diffraction（XRD） and luminescent spectra. The results of XRD show that NaLa9（1-x）（SiO4）6O2：9xDy^3＋ phosphors have been synthesized successfully. The results of fluorescence spectra show that the optimum doping concentration x（Dy^3＋） = 0. 03 for phosphors NaLa9（1-x）（SiO4）6O2：9xDy^3＋,respectively.
