摘要：
Tb3+ doped glass ceramics containing SrWO4 crystals are prepared by melting crystallization method and their luminescence properties are studied. It is determined by DSC that the heat treatment temperature is 730 degrees C and the time is 2h. Through the XRD of the glass ceramics, it can determine the crystalize phase is SrWO4 after comparing with PDF normal card. In the emission spectrum of the Tb3+ doped SrWO4 glass ceramics samples, there are two obvious emission peaks at 490nm and 544nm corresponding to the transitions of D-5(4)-> F-7(6) and D-5(4)-> F-7(5) of Tb3+. Based on the fluorescence spectrum, it can be determined that the optimum concentration of Tb4O7 is 1.0 mol, and the fluorescence lifetime is 2.16 ms.
