Ca8La2(1 − x)(PO4)6O2:xCe (x = 0.1, 0.3, 1, 3, and 10%) single crystals were synthesized by the floating zone method, and their photoluminescence and scintillation properties were investigated. X-ray diffraction patterns confirmed that all the samples had a single phase without any impurity phases. All the samples showed an emission peak due to 5d-4f transitions of Ce3+ ions under UV and X-ray irradiations. According to the pulse height spectra, the light yield of the 1% Ce-doped sample was estimated to be 30 photons/MeV under 241Am α-ray irradiation.
