Abstract
A series of PbWO4 crystals, grown consistently from one melt, were studied under excitation by VUV and X-ray synchrotron radiation. We observed a systematic change in the spectroscopic data (emission spectra, luminescence decay, thermoluminescence, radiation hardness) from the first grown to the last. In the reflectivity spectrum, the intensity in the 4–6 eV absorption region, which is assigned to the Pb2+ 6s–6p transitions, decreases relative to the intensity in the 7–10 eV region which is due to (WO4)2− absorption. We connect these changes with the variation in stoichiometry of the melt during crystal growth.
