摘要
通过高温固相法制备出Ba_(2)MgGe_(2)O_(7)固体荧光粉,采用实验研究方法进行分析测定,其中包括对所得BMGO荧光粉进行荧光光谱分析,了解掺杂离子不同含量下各个样品的光学性能,分析解释BMGO荧光粉通过掺杂Bi^(3+)、Eu^(3+)后,样品发射光谱强度大大提高,呈现稀土铕离子的特征峰,具有荧光效应的显著特点;分析系列荧光粉的粉末X射线衍射光谱,探究掺杂新离子后,BMGO的晶态物质的物相分析,晶态物质组成元素是否有结构差异;CIE色度图和荧光光谱显示,样品含量为Ba_(2)MgGe_(2)O_(7):0.01%Bi^(3+),4%Eu^(3+)荧光强度最高,色纯度接近正红色。
Ba_(2)MgGe_(2)O_(7) solid fluorescent powder was prepared by high-temperature solid-state method,and experimental research methods were used for analysis and determination.This included analyzing the fluorescence spectra of the obtained BMGO fluorescent powder to further understand the optical properties of each sample under different concentrations of doped ions.The analysis explained the significant enhancement of the emission spectral intensity and fluorescence effect of the BMGO fluorescent powder after doping with Bi^(3+)and Eu^(3+);the powder X-ray diffraction spectrum of this series of fluorescent powders was analyzed,the phase analysis of the crystalline substance of BMGO was explored after doping with new ions,and whether there were structural differences in the constituent elements of the crystalline substance was determined;According to the CIE chromaticity diagram and fluorescence spectrum,the sample concentration is Ba_(2)MgGe_(2)O_(7):0.01%Bi^(3+),4%Eu^(3+)having the highest fluorescence intensity and a color purity close to true red.
