SrWO4∶Gd3+,Tb3+荧光粉的发光性质及能量传递∗
Luminescence Properties and Energy Transfer of SrWO4∶Gd3+,Tb3+
摘要
Abstract
One serie SrWO4∶Gd3+,Tb3+ fluorescent powder were synthesized in this paper. The structure,mor-phology and luminescence properties of the samples were characterized by XRD,SEM and luminescence spectrosco-py. XRD analysis confirmed the samples exhibited a body-centered tetragonal crystal structure. The particles of as-synthesized phosphors are basically spherical in shape,and well dispersed with the mean particle size of 3μm. In the emission spectrum of Sr0. 9 WO4∶0. 05Gd3+,0. 05Tb3+ excited by 223nm, the main peak is located at about 549nm due to the transition of 5 D4→7 F5 of Tb3+ emission. The PL intensity of Tb3+ in Sr0. 9 WO4∶0. 05Gd3+, 0. 05Tb3+ increases with the increase of x values due to an energy migration process like Gd3+→Tb3+occurred in the phosphors.关键词
