Abstract

We report on the long-lasting phosphorescence in Ti-doped BaZrO₃ perovskite-type crystals (synthesized by a solid-state reaction method). The phosphorescence color is blue and the phosphorescence can still be seen with the naked eye for 30 minutes or more in the dark after stopping UV light. By the measurement of electron spin resonance (ESR) spectra, it was confirmed that the defects of F⁺ center and Zr³⁺ exist in the Ti: BaZrO₃ and their concentrations decrease with the additive amount of TiO₂. It is expected that the luminescence center is F_A center composed of Ti³⁺ and F⁺ center.
