Preparation of Photostimulable Phosphor Ceramics Using Spark Plasma Sintering(SPS) Method

Abstract

  Photostimulable phosphor materials such as KBr:Eu₂O₃, RbBr:Eu₂O₃, NaBr:Eu₂O₃, KCl:EuCl₃, and SrAl₂O₄:Eu₂O₃, which can be used as storage phosphor materials for the imaging plate(IP), were, for the first time, prepared using the spark plasma sintering (SPS) method. The photostimulated luminescence(PSL) and its fading characteristics of these phosphor materials are reported. It was found that the phosphors can be prepared using SPS method at lower sintering temperature and for shorter time in comparison with conventional sintering method using thermal energy.
