Radiation response characteristics of organic–inorganic perovskite-type compounds with a chlorophenethylamine
Source abstract
Abstract
Abstract We fabricated crystals of organic–inorganic layered perovskite-type compounds with a chlorophenethylamine (nCl-C6H4C2H4NH3)2PbBr4 (n = 2, 3, 4) by a temperature gradient method, and evaluated their photoluminescence and radiation response characteristics. An emission peak due to exciton emissions with a decay time constant of several nanoseconds was clearly detected in the fabricated perovskite-type compounds with a chlorophenethylamine. Furthermore, some broad emission peaks possibly due to bound excitons trapped at unknown defects with a decay time of approximately twenty nanoseconds were also observed in the perovskite-compounds with a chlorophenethylamine, especially 2-chlorophenethylamine. Moreover, the pulse height spectra under 241Am gamma-ray irradiation (about 60 keV) showed that the scintillation light yields of the (2Cl-C6H4C2H4NH3)2PbBr4, (3Cl-C6H4C2H4NH3)2PbBr4 and (4Cl-C6H4C2H4NH3)2PbBr4 were 7500, 5000 and 8300 photons/MeV, respectively. In addition, the perovskite-compounds with a chlorophenethylamine exhibited low afterglow levels about 10 ppm, and the low levels were found to be comparable to an afterglow level of Ce-doped Gd2SiO5.
