摘要：

We discuss the synthesis of Na2W2O7 polycrystalline materials based on the TG-DSC experiment. The luminescence properties of the Na2W2O7 crystal are investigated using the Nd:YAG laser as the excitation source. It is found that the maximum emission peak of the Na2W2O7 crystal is at 525 nm. The 525-nm luminescence decay has two components. One has decay time 1.8 mu s and the other 49.1 mu s. By comparing this results with that of the Na2W2O7 crystal, it is assumed that the 525-nm luminescence emission of the Na2W2O7 crystal originates from the WO66- octahedral group.
