摘要：
Tb3+ doped transparent glass ceramics (GC) containing Gd4.67(SiO4)3O nanocrystals with the diameterof approximately 30 nm were prepared by a melt-quenching method and subsequent thermal treatment. Their microstructural and optical properties were investigated. After thermal treatment, the photoluminescence and X-ray excited luminescence intensities of Tb3+ doped GC containing Gd4.67(SiO4)3O nanocrystals both areenhanced. The light yield of GC is approximately 38% of commercial Bi4Ge3O12 scintillator with the same thickness, benefiting from a preferential incorporation of Tb3+ into crystallized Gd4.67(SiO4)3O nanocrystals with a low phonon energy. Moreover, GCpossessesa high density of 4.9 g/cm3. © 2019, Editorial Department of Journal of the Chinese Ceramic Society. All right reserved.
