In this study, SrZrO3 single crystals doped with 0, 0.3, 1.0, and 3.0% Ti were successfully synthesized by the floating zone method, and their optical and scintillation properties were investigated. Both the photoluminescence (PL) and scintillation spectra revealed a broad emission band centered at 400 nm, and the decay time constants were of µs order. All the Ti-doped specimens exhibited clear full energy peaks under 241Am α-ray irradiation. The obtained PL quantum yield and pulse height spectra suggest that the optimum Ti concentration among our specimens is 3.0%.
