摘要	Long persistence phosphor powder of Eu2+, Dy3+ co-doped SrAl2O4 were prepared by combustion method. The influence of boric acid with different contents on the luminescent properties of Eu2+, Dy3+ co-doped alkaline earth aluminates were studied. To analyze the role of B2O3, phase identification was carried out by X-ray powder diffraction, emission spectra were recorded using a luminescence spectrometer, and luminescence photos were taken in a dark room after being excited by UV. The results indicated that the λ on of the sample with content of 0.8 is 518 nm, which is the typical emission of Eu2+ 4f5d &rarr 4f and is a wide emission spectrum. There are two peaks in the emission spectra of the sample with content of 2, one is at 518 nm, and the other is at 487 nm, both of which are weak. The whole spectral line is a declining line. With the increase in boric acid content, the luminescence property and appearance character of Eu2+, Dy3+ co-doped strontium aluminates long persistence phosphor were different. In some range, with the increase in boric acid content, luminescence property and luminescence intensity were increased, and the sintering temperature was lowed.
