X-ray excited luminescence, photoluminescence decay and thermally stimulated luminescence (TSL) measurements have been performed on a selected set of PbWO 4 single crystals. At room temperature the X-ray excited emission spectrum is characterized by two components peaking at about 2.5 and 3.1 eV. Th
PbWO 4 has recently attracted much attention because of its scintillation applications. We have measured its dielectric response subsequent to Ar + and UV irradiation, respectively. Dielectric relaxation was observed, which we attribute to a complex color center in the WO ~2 tetrahedron. The complex
