Preparation and Performance Study of New Double Doped Red Fluorescent Powder Ba2MgGe2O7∶xBi3+,yEu3+
Ba2MgGe2O7 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 Bi3+and Eu3+;the powder X-ray diffraction spectrum of this series of fluores-cent powders was analyzed,the phase analysis of the crystalline substance of BMGO was explored after doping with new i-ons,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 Ba2MgGe2O7:0.01％Bi3+,4％Eu3+having the highest fluorescence intensity and a color purity close to true red.
