Paper Abstract

We found that an intense yellow photostimulated luminescence (PSL) can be observed when UV-light or visible-light irradiated SrS:Eu,Sm and CaS:Eu,Sm phosphor ceramics are estimated with IR light with wavelength from 800 nm to 1700 nm. This phenomenon in these phosphor materials is applicable to a novel 2D IR sensor. In the paper, we describe PSL characteristics in SrS:Eu,Sm and CaS:Eu,Sm phosphor ceramics, especially in SrS:Eu,Sm phosphor ceramics, and discuss the mechanism of the PSL which is observed by stimulating the phosphor with IR light.
