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.
