Scintillators emitting near-infrared (NIR) photons have unique characteristics and have been attracting attention recently. For example, scintillators emitting NIR photons are expected to be an effective tool for radiation dose monitoring in high-dose environments. In this study, YAlO3 samples doped with various rare-earth ions (Er3+, Ho3+, Pr3+ and Tm3+) were synthesized by the floating zone method and their scintillation properties from the UV to NIR range were evaluated. As a scintillation detector property, the Er3+-doped sample indicated an approximately linear proportional relationship from 1 mGy to 10 Gy.
