Paper Abstract

An efficient photostimulated luminescence (PSL) with a peak at about 420 nm is observed by stimulating ultra-violet (UV)-ray-irradiated europium-doped potassium chloride (KCl:Eu) crystalline phosphor with 560 - 580 nm light. The excitation and emission mechanism for the 420 nm PSL in UV-ray irradiated KCl:Eu phosphors are proposed. It is found that the PSL intensity increased with increasing irradiation dose of UV-ray, which indicating that the KCl:Eu is one of the most attractive candidates for two-dimensional UV-ray imaging sensor utilizing PSL phenomenon.
