| 中文摘要 | The photoacoustic spectrum, which is performed for the first time, optical reflection, and excitation and emission spectra of undoped PbWO4 powders with different annealing atmospheres were compared and analyzed. The red shifts of the absorption edge and the increased absorption around 425 and 600-800 nm in the vacuum annealed sample with respect to that in the oxygen annealed sample indicate the decrease of the O- centers in the sample. The increase of the blue luminescence in a vacuum annealing atmosphere suggests that annealing under vacuum atmosphere produces PbWO4 crystals with a better light yield.
