Sumario:[Image: see text] The luminescence properties of Ba(13.35)Al(30.7)Si(5.3)O(70):Eu(2+) and Ba(13.35)Al(30.7)Si(5.3)O(70):Eu(2+),Tm(3+) phosphors are presented. After being excited by a light source, Ba(13.35)Al(30.7)Si(5.3)O(70):Eu(2+),Tm(3+) phosphors emit intense yellow long persistent luminescence covering the region from 450 to 700 nm, which can last about 8 h. Thermoluminescence curves were demonstrated to analyze the trapping nature of persistent luminescence. Tm(3+) is added to improve the long persistent luminescence properties of phosphors. The mechanism of persistent luminescence has been studied.
