Abstract

We report a large enhancement of yellow photostimulated luminescence (PSL) by codoping ${Tm}^{3 +}$ in ${Sr}_{3} {SiO}_{5} : {Eu}^{2 +}$ upon infrared stimulation at 980 nm after pre-exposure in Ultraviolet light. The initial PSL intensity and light storage capacity are enhanced by a factor of 33 and 2, respectively, for ${Tm}^{3 +}$ concentration at 0.0004. The thermoluminescence spectra indicate that codoping ${Tm}^{3 +}$ generates a trap peaking at 385 K. The trap is much more sensitive to infrared light than the original one, so that the light storage period of the material is beyond tens of days with the minimum detectable infrared power density only $54 μW / {cm}^{2}$ .
