Effect of organic moieties on the scintillation properties of organic–inorganic layered perovskite-type compounds

Abstract

Abstract The effects of organic moieties on the scintillation properties of organic–inorganic layered perovskite-type compounds have been investigated. Three kinds of single crystals were fabricated, namely, (C 4 H 9 NH 3 ) 2 PbBr 4 (C4), (C 6 H 5 CH 2 NH 3 ) 2 PbBr 4 (Ben), and (C 6 H 5 C 2 H 4 NH 3 ) 2 PbBr 4 (Phe). Among the single crystals, the light output of Phe was found to have the greatest value when exposed to X-ray radiation (67.4 keV). The light output of Phe was 0.62 times that of YAP:Ce. The relative values of the light outputs among the fabricated single crystals under X-ray radiation correlated well with those of the quantum efficiencies and the luminescence intensity under ultraviolet radiation.
