摘要：
Samples of non-stoichiometric PbWO4 crystals were annealed and their surfaces were then brushed and polished. Comparison of the changes in emission and absorption spectra resulted in finding the connections between the emissions R, G(I), and G(II), and the absorption centers 330/355 occupied by 2, 1, and 0 oxygen atoms or ions, respectively.
