摘要
The Eu 3+ doped Na 24 As 2Mo 22 O 83 phosphor was prepared by solid state reaction from Na 3AsO 4·12H 2O?Na 2MoO 4·2H 2O and MoO 3,and characterized by using elemental analysis,infrared spectroscopy and powder X ray diffractometry.According to our measurements with X ray diffraction,this material belongs to orthorhombic system with its lattice contants:a=1.4824nm,b=1.1902nm,c=1.1042nm,that are consistent with space group D 4 2 P2 12 12 1(No.19).The emission and excitation spectra were also measured.The luminescence properties of Eu 3+ doped Na 24 As 2Mo 22 O 83 and energy transfer mechanism were discussed.
