Glass preparation and temperature-induced crystallization in multicomponent B2O3–PbX2–PbO–Al2O3–WO3–Dy2O3 (X = F, Cl, Br) system

Abstract
Abstract Multicomponent lead borate glasses modified by PbX 2 (X = F, Cl or Br) were examined. For the first time, lead tungstate PbWO 4 crystallites dispersed into glass matrices were successfully obtained from controlled crystallization. Excitation by 310 nm line leads to broad blue luminescence related to the radiative transition which occurred in the PbWO 4 crystallites. It was found that halogen X ions (X = F, Cl or Br) were also incorporated in the distorted crystal system of PbWO 4 . It was proved by results obtained from X-ray diffraction as well as luminescence measurements.
