Abstract

It is demonstrated that the commercially-available imaging plate (IP) using BaFBr:Eu photostimulable phosphor is useful as a phosphore material for 2D UV image sensor though the sensitivity of the IP for UV-ray is not so high. The new phosphore materials as alternative materials for the IP are surveyed for many possible phosphore materials and consequently we find out that the Ca_xSr_1-xS:Eu,Sm phosphore ceramics exhibited a high photo stimulated luminescence (PSL) intensity for UV-ray irradiation. It is found that the SrS:Eu,Sm phosphore ceramics exhibits good PSL characteristics for UV-ray imaging and the PSL characteristics are depended on the content of CaS and the concentration of Eu and Sm doped.
