Abstract
Fluorozirconate-phosphate glasses of the ZrF4–BaF2–NaPO3(LiPO3) and ZrF4–BaF2–LaF3–AlF3–LiPO3 systems doped with EuF3, ErF3, and NdF3 were studied by the differential-thermal (DTA) and X-ray diffraction (XRD) analysis, luminescence spectroscopy, scanning and transmission electron microscopy (SEM and TEM) methods. Addition of the phosphate component up to 20 mol % decreases the glass transition temperature and increases the glass stability to crystallization. Heat treatment in the range >Tg–Tc1 of glass transition and first maxima of crystallization temperatures causes crystallization of nanosized β-BaZrF6 particles. At LiPO3 (NaPO3) concentrations of more than 80 mol %, glasses containing a crystalline phase are formed during the synthesis process.
