Vacuum UV- and Radiation-induced Luminescence Properties of Sr3Y(PO4)3 Synthesized by Optical Floating Zone Technique
A Sr 3 Y(PO 4 ) 3 single crystal was grown by the optical floating zone technique using four xenon arc lamps.The photoluminescence and scintillation properties in the vacuum ultraviolet (VUV)-visible range were investigated.A broad emission peak appeared at 300-600 nm under the irradiation of both VUV light and X-rays.The scintillation decay time constants were obtained to be 40 and 370 ms.They would be respectively related to self-trapped excitons and some defects.The light yield and energy resolution of Sr 3 Y(PO 4 ) 3 were revealed to be 260 photons/5.5MeV- and 19%, respectively, by measuring pulse height spectra of 241 Am -rays (5.5 MeV).
