Abstract

Frequency and temperature dependent dielectric dispersion of 20PbF₂-20TeO₂-(60-x)B₂O₃-xEu₂O₃(x=0 to 2.5, mole fraction, %) glasses prepared by the melt-quenching technique were investigated in the frequency range 1 Hz-10 MHz and temperature range 313-773 K. Dielectric relaxation dynamics was analyzed based on the electric modulus behavior. Dielectric losses (tan δ) are found to be negligibly small in the temperature range 313-523 K, proving good thermal stability of the glasses. The present Eu₂O₃-doped oxyfluroborate glasses showed low dielectric loss at higher frequency and lower temperature, proving their suitability for nonlinear optical materials.
