Pr-doped scintillators are attracting attention because of their potential applications in medical devices. In this study, we focused on Pr-doped (La, Y)2Si2O7 scintillators to grow single crystals by the micro-pulling-down method and to evaluate their optical and scintillation properties. From the powder XRD results, the crystal structure and the space group were identified to be monoclinic and P21/n, respectively. The results of optical and scintillation characterization show that the luminescence from the Pr3+ 5d1–4f transition increases with increasing Pr3+ concentration. The maximum light yield was also obtained for the sample with the highest Pr3+ concentration. The Pr-doped (La, Y)2Si2O7 single crystal shows promising properties for application in radiation detection.
