Abstract: |
The Sm3+ doped ZnO-Al2O3-SiO2 system glass-ceramics were prepared by melting and crystallization. Its heat treatment system in different conditions were studied. The micro-structure and optical properties were studied by differential scanning calorimetry (DSC), X-ray diffraction (XRD), scanning electron microscopy (SEM), UV - visible - near infrared spectrophotometer (UV-Vis-NIR), fluorescence spectroscopy. The results show that the optimized heat treating system of Sm3+ doped ZnO-Al2O3-SiO2 system(ZAS) glass is 730℃×1h, the main crystal phase is Zn2SiO4, and the second phase is ZnAl2O4. The grain diameter observed by SEM is 10-15 nm, the optical transmittance reaches about 86% in near-infrared region.
