Structural, optical and dielectric properties of glass-nanocomposite
Transparent glass-nanocomposite sample [50Li 2B 4O 7–50(SrO–Bi 2O 3–Nb 2O 5)] (mol %) was prepared by a conventional melt-quenching technique. Fluorite (Bi 3NbO 7) and SrBi 2Nb 2O 9 (SBN) was produced by heat-treating the as-prepared sample at 773 K for 6 h (HT773). The nanocrystallites of fluorite...
