Lead borate oxyfluoride glasses doped with Nd ~(3+) ions and transparent glass-crystal materials based on them

摘要

This paper discusses the properties of synthesized lead borate oxyfluoride PbF _2-PbO-B _2O _3 glasses doped with Nd ~(3+) ions at concentrations from 0:6 × 10 ~(20) to 25 × 10 ~(20) cm ~(-3). The possibility of using them as a basis for obtaining transparent glass-crystal materials by controlled crystallization with precipitation of the fluoride crystalline phase is studied. The changes in the structure and optical properties of the glass-crystalline material by comparison with the initial glasses were monitored by X-ray phase analysis and Raman spectroscopy and by investigating the fluorescence characteristics of the Nd ~(3+) ions.
