Synthesis and characterization of nanosized SrAl2O4:Eu2+,Dy3+long afterglow luminescent material
摘要
Abstract
SrAl2O4Eu2+, Dy3+long afterglow luminescent material was synthesized by glycine-nitrate process. The effect of molar ratio of glycine to metal ion(G/M)on the structure and properties of SrAl2O4Eu2+,Dy3+was investigated. The results indicate that with the increase of G/M, the particle sizes and emission intensity increase, emission spectra are shift to red wavelength, and initial brightness first increases and then decreases. It is found that single SrAl2O4 phase powders with mean particle size of 75 nm are obtained when a G/M ratio of 3∶1 is adopted, and show the highest initial brightness. The main emission peaks appear at 508 nm, and the emission spectra of the synthesized luminescent materials show that they are broadband, which is the typical emission of Eu2+4 f 5 d→4 f.关键词
