摘　　要：本文报道了新型发光晶体Na_5Pr(WO_4)_4的生长及Pr^(3+)离子的光谱性质。测定了该晶体的结构以及吸收光谱、荧光光谱和激发光谱。研究表明,该晶体有可能成为继Na_5Nd(WO_4)_4晶体之后又一激光晶体新品种。Speetroscopic properties of Pr3+ ion and Na5Pr(W04)4 crystal are reported. The crystal belongs to the tetragonal system, with space group I41/a and cell parameters a= 1.l563nm, c=1.1468 nm. The absorption, fluorescence, excitation and infrared spectra of such crystal were measured and analyzed at room temperature. The strong fluorescence emission of high colour purity of such crystal suggests that it would be a novel laser material.
