摘要：

B2O3-Bi2O3-SiO2-Sm2O3 glasses have been synthesized by melt quench technique for different mol% Sm2O3. The electrical behavior of these glasses was studied by impedance spectroscopy technique at room temperature, covering the frequency range between 1 M and 1 GHz. In addition, dielectric measurements were made to evaluate the dependence of the dielectric constant different Sm ions. The dielectric constant is approximately 3200 at room temperature for 0.5 mol% Sm-doped compositions at 645 MHz frequency. The results show significant variations for the real part and large variations for the imaginary part among different frequency with different Sm fractions. Complex impedance analysis was used to estimate its electrical conductivity as well as its corresponding optical properties.
