A novel electron trapping material of CaB4O7:Sm3+ was synthesized by high temperature solid-state reaction, and its characterization and luminescent properties were investigated at room temperature. The results indicate that ultraviolet light can be used as exciting source to store energy. After exposed under ultraviolet, the sample was stimulated by 980nm laser. As a result, an obvious luminescence at 556, 596 and 643 nm were detected. The photo-stimulated emission spectrum was three bands peaking at 562, 599 and 646 nm that are the characteristic emission of Sm3+ ions due to the f→f transitions 4G5/2→6HJ (J = 5/2, 7/2, 9/2), respectively. The TL glow curve contains two overlapping glow peaks at around 541 and 598 K.was synthesized by high temperature solid-state reaction, and its characterization and luminescent properties were investigated at room temperature.
