Abstract

Sm3+ doped B2O3-Li2O-Nb2O5 glass was prepared by the conventional melting method in air atmosphere. The glassy nature of as-prepared glass was established by differential thermal analysis. X-ray powder diffraction confirmed crystallization behavior and process in heat-treated glass ceramic samples. Ferroelectric hoops were detected in glass ceramic samples which were heat treated at 500℃ and 550℃. Compared to as-prepared glass, luminescence behavior was improved in transparent glass ceramic samples that were heat treated at 500℃. Crystallization of ferroelectric phase optimized ferroelectric and luminescence properties at the same time. Therefore this glass ceramic system can be a potential new material for combining ferroelectric and optical properties.
