Preparation and Optical Properties of Er3+-Yb3+ Co-Doped ZnO-B2O3- SiO2 -TiO2Transparent Glass-Ceramics
Abstract:
Er3+-Yb3+ co-doped ZnO-B2O3- SiO2-TiO2 transparent glass ceramics were synthesized by melt crystallization technique. Samples were characterized by DSC, XRD, SEM, UV-Vis-NIR and fluorescence spectra and the factors affecting the crystallization of glass ceramics were analyzed. The results indicated good crystallization property of ZBS glass ceramics. The optimum crystallization temperature was 800°C, and crystallization time was 60 min. The main crystal phase was Zn2TiO4 and the transmittance was up to 70% in visible light region. SEM micrograph indicated that the grain diameter was less than 100nm and the emission spectrum of glass ceramics displayed by fluorescence spectra was greatly improved compared with matrix glass. Strong emission peak was observed at 1535nm.
