Thermal Stability and Optical Properties of Er3+ Doped BaTi2O5 Glasses

Abstract:

Article Preview

Er3+ doped BaTi2O5 spherical glasses were prepared using a containerless processing with an aerodynamic levitation furnace. These glasses were found to have high solubility of Er3+ and the substitution ratio of Er3+ for Ba2+ reached 30 %. Differential scanning calorimetry measurements revealed that the glass transition temperature Tg and the crystallization onset temperature Tx shifted to high temperatures and the value of T (= Tx – Tg) increased with substitution of Er3+, indicating that the stability against crystallization improved. We found that these glasses had high refractive indices exceeding 2.1 with low Abbe numbers of approximately 20.
