Abstract
MoO3 incorporated sodium-lime-silicate glasses of composition 55SiO2 - 25Na2O - 5CaO - 10ZnO - 5MgO(1-x): MoO3 (x) (x = 0, 0.1, 0.3, 0.5, and 1) were prepared using the melt-quench technique. The transmittance and absorbance spectrum of the glasses were detected by UV–VIS spectroscopy between the wavelength range of 250–900 nm. The optical transmittance of the doped glasses was significantly enhanced by adding MoO3 to the base glass structure. The indirect band gap (Eg) and Urbach energy (EU) values have been evaluated with the help of absorption spectra. Band gaps range from 3.478 to 3.752 eV, and Urbach energies range from 0.223 to 0.709 eV. Advanced optical characterization of glasses was obtained using standard equations by analyzing important optical parameters such as molar volume, refractive index, optical dielectric constant, molar refraction, electronic polarizability, and metallization criterion. All the data has been discussed in accordance with the MoO3 contributions. The glass structure with 0.1 % MoO3 doped, coded as M-01, showed a different change in the measurements and calculations than the other glasses. The glass structure under consideration exhibits superior characteristics in terms of light transmittance, band gap value, and metallization criterion, while displaying comparatively lower values for Urbach energy, refractive index, optical dielectric constant, and electronic polarizability.
