| Abstract | We report the observation of long lasting yellow phosphorescence and photostimulated luminescence (PSL) in Sr3SiO5 : Eu2+ and Sr3SiO5 : Eu2+, Dy3+ phosphors. The decay patterns of phosphorescence and thermoluminescence curves demonstrate that introduction of Dy3+ into Sr3SiO5 : Eu2+ can generate a large number of shallow traps and deep traps. The generated deep traps prolong the phosphorescence up to 6 h after UV irradiation. The PSL is studied under 808 nm excitation. Slow rising and falling edges of the emission in Sr3SiO5 : Eu2+, Dy3+ are observed, showing a retrapping process by the generated shallow traps due to co-doping Dy3+. |
