Abstract

We report a large enhancement of yellow photostimulated luminescence (PSL) by codoping Tm3+ in Sr3SiO5:Eu2+ 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 Tm3+ concentration at 0.0004. The thermoluminescence spectra indicate that codoping Tm3+ 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/cm2.
