Abstract: 
The nature of the green emission of PbWO4 is still under discussion, models ranging from WO3 groups over lead deficient phases to local distortions towards a wolframite structure. In CaWO4 and PbMoO4 optically detected magnetic resonance proved, using resolved Mo hyperfine structure, that tetrahedral MoO4 complexes give rise to a green luminescence. Based on this, we have performed such experiments on a series of PWO samples from various sources and with different dopants. In all cases, we find resonances typical for MoO4 groups, however, with strongly varying intensity depending on the Mo content of the crystals. These ODMR signals are connected with a luminescence band with a half width of 0.43 eV peaking at 508 nm. (C) 2001 Elsevier Science Ltd. All rights reserved.
