Outline of Final Research Achievements

This study is about development of near-infrared emitted scintillators using Nd3+-doped perovskite crystals. The study was performed with the evaluation of the optical properties (transmittance, reflectance, refraction、PL) and radiation response properties (radioluminescence, decay time, light yield, temperature dependency, dose response, TL, OSL). As a result of the study, we found that the 0.5-1.0 mol% Nd-doped (Y, Lu)AlO3 crystals indicate excellent scintillation performance such as high transmittance in the near-infrared regions, high detection efficiency, high emission intensity, good dose response.
