Development of phosphors for ionizing radiation detection

Abstract

To detect ionizing radiations efficiently, bulk phosphor materials, including single crystals, opaque and transparent ceramics, and glasses, have been used. Phosphors for ionizing radiation detection are classified into two groups such as scintillators and storage phosphors. In terms of the emission intensity, an inverse correlation of scintillation and storage luminescence has been confirmed in many materials. Based on such a relationship, many new phosphors for ionizing radiations have been developed, and some selected results are shown.
