摘　　要：Thermal stimulated luminescence (TSL) and photostimulated luminescence (PSL) were used to investigate the luminescent performance of Al 3+ doped BaFBr∶Eu 2+ in different synthetic conditions. Theory analysis shows that the decay of TSL spectra is different from that of PSL spectra. Theoretical calculation was used to investigate the effects of energy state in Al 3+ doped BaFBr∶Eu 2+ by different synthetic conditions. The relationship of color center’s energy and different synthetic conditions is discussed.Thermal stimulated luminescence (TSL) and photostimulated luminescence (PSL) were used to investigate the luminescent performance of Al 3+ doped BaFBr∶Eu 2+ in different synthetic conditions.
