Preparation and Luminescence Properties of Eu³⁺ Doped Niobium Silicate Glass Ceramics

Abstract:

niobium silicate glass with the mass composition of 35SiO₂-25Nb₂O₅-20Na₂O-10K₂O- 7B₂O₃-3Eu₂O₃ was synthesized by a traditional glass melting method. Glass ceramics containing Na₂Nb₈O₂₁ nanocrystals were prepared by heat treating the glass samples. The results of X-ray diffraction (XRD) indicated that the crystallite in the glass ceramics is Na₂Nb₈O₂₁ nanocrystals. The luminescence spectra showed the emission intensity of Eu³⁺ doped glass ceramics was stronger than that of the glass matrix, and increased with the heat treatment temperature increasing..The transmittance of the glass ceramics can be up to 80% in the near-infrared light area.
