Synthesis and different optical properties of Gd 2 O 3 doped sodium zinc tellurite glasses

Abstract

Optical properties of a series of Gd 2 O 3 doped sodium zinc tellurite [xGd 2 O 3 -(0.8-x) TeO 2 -0.1Na 2 O-0.1ZnO] glasses prepared by conventional melt quenching method have been studied. UV-Vis spectrophotometer was used in the integrating sphere mode at room temperature to study the effect of Gd 2 O 3 doping on the optical band gap, refractive index, dielectric constant and susceptibility within the wavelength range from 230-800 nm. Density is measured using Archimedes principle for the calculation of molar volume, molar refraction, polarizability and metallization criterion of the glasses.

Cerium (IV) oxide reinforced Lithium-Borotellurite glasses: A characterization study through physical, optical, structural and radiation shielding properties

“…In one of our previous studies that we have conducted on similar Li 2 O-B 2 O 3 -TeO 2 glasses containing Gd 2 O 3 [32], decrease in NBOs within the glass increased the optical band gap. However, in this study in which CeO 2 amount was increased, it can be said that NBO ratio increased and correspondingly the structure became more ionic and as a result, optical band gap decreased [36]. Increase in the number of NBOs renders the structure more open, and molar volume increase with doping can indicated to be the proof of the structures becoming more open.…”

Composition-Dependent Optical and Photoelectrochemical Behavior of Antimony Oxide Iodides

“…Bandgaps of the materials were determined by using the Tauc analysis. 49,50 The direct bandgap of Sb 3 O 4 I, Sb 8 O 11 I 2 and Sb 5 O 7 I are estimated to be 2.16 eV and 2.74 eV, 2.85 eV and 3.25 eV, respectively (Fig. 5b).…”

Impact of Gd2O3 Incorporation in Structural, Optical, Thermal, Mechanical, and Radiation Blocking Nature in HMO Boro-Tellurite Glasses

“…The refractive index continuously increased with doping Gd 2 O 3 . The refractive index was influenced by a larger atomic radius (1.79 Å) of Gd [10] which is greater than that of tellurium (1.6 Å) and boron (0.98 Å). The higher polarization ability of cations resulting from higher cation radius of Gd 3+ ions induces high n values, providing a platform for current Gd 3+ -doped glasses in the non-linear optical application.…”
