Abstract
In this work, a new approach has been developed to correlate the relation between both the optical and electrical conductivities of some cerium sodium borate glasses that have been prepared using the traditional fast quenching technique. The amorphous nature has been proven for all studied samples based on their X-ray diffraction patterns. Lorentz–Drude and Cole–Cole models have been used to fit both the optical conductivity and the optical dielectric parameters, respectively. The extraction of the terahertz parameters was performed using UV–Vis spectra while the calculated electrical conductivity has been fitted using different theoretical models. The correlated barrier hopping CBH model is considered as the applicable conduction mechanism for the studied cerium sodium borate glasses. The increase in CeO
2
content caused an increase in the values of the optical transmittance, the plasmon frequency, the dielectric activation energy, barrier height, the exponent factor, and the characteristic relaxation time. On the other hand, the increase in CeO
2
content caused a decrease in the values of the optical reflectance, the linear refractive index, the optical dielectric constant, and electrical and optical conductivities.
