Synthesis and luminescent properties of red-emitting Ba3-xAl2O6:xEu3+ phosphor

Abstract

Abstract: Ba₃Al₂O₆:Eu³⁺ phosphor has been prepared by solid state reaction method. X-ray powder diffraction (XRD) analysis confirmed the phase formation of BaAl₂O₆:Eu³⁺ and the doping of Eu³⁺ did not change the crystal structure. The scanning electron microscope (SEM) image exhibited the irregular morphology of Ba₃Al₂O₆:Eu³⁺ particles, the particle diameter of the sample is not very uniform, and there is a reunion phenomenon. The photoluminescence excitation (PLE) and emission (PL) spectra were investigated. The fluorescence spectra showed that the fluorescence powder produced by Eu³⁺ was the highest when the doping concentration of Eu³⁺ was 9 mol%.
