Abstract: Ca 8 La 2(1 -x) (PO 4 ) 6 O 2 :xCe (x = 0.1, 0.3, 1, 3, and 10%) single crystals were synthesized by the f loating 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 Ce 3+ 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 241 Am α-ray irradiation.
