我们报道了掺杂和未掺杂的pbmoo4和pbwo4单晶的发光特性；首次发现了PbMoO4的红色辐射。测量了pbwo4发射和pbmoo4短波长的偏振度。波长较短的发射被分配到四面体MoO42−(WO42−)基团中的3t11a1跃迁。假设3t1能级由于自旋-轨道耦合而分裂。波长较长的发射被分配到缺乏氧离子的钼酸盐（钨酸盐）基团中的跃迁，即MoO3（WO3）基团。
We report on the luminescence of doped and undoped PbMoO4and PbWO4single crystals; a red emission is found for the first time for PbMoO4. The degree of polarization of both the emissions of PbWO4and of the shorter-wavelength emission of PbMoO4is measured. The shorter-wavelength emissions are assigned to the3T11A1transition in the tetrahedral MoO42−(WO42−) group. It is assumed that the3T1level is split due to spin-orbit coupling. The longer-wavelength emissions are assigned to a transition in a molybdate (tungstate) group lacking an oxygen ion, i.e., a MoO3(WO3) group.
