“…The free volume in the glasses gives a fact of openness in the glasses which is the characteristic nature of glasses having consistent structure. Figure 6, shows the reduction in microhardness and which reveals the presence of non-bridging oxygen ion(NBO) and this causes the formation of a soft glassy network [39][40][41][42]. For solid materials, Debye temperature (θD) is another vital parameter, which relates the atomic vibrations.…”

The glass series of xEu2O3-5PbO-25TeO2-(70-x) B2O3, where x=0.1 mol% to 0.6 mol% were prepared by employing the conventional melt quenching method. The non-crystallinity of prepared BTE glasses was examined by the X-ray diffraction method. The very important mechanical properties such as elastic moduli, Debye temperature, Poisson’s ratio, fractional bond connectivity, softening temperature, acoustic impedance, and the thermal expansion coefficient of the BTE glasses have been studied by measuring ultrasonic velocity. The experimental results indicate that the calculated parameters strongly depend on increasing Eu2O3 concentration. The elastic moduli of the prepared samples were found to decrease with Eu2O3 concentration and this increases the discontinuity in the glass network.

“…Because of its unique qualities, tellurite 274 glass has been introduced. When compared to oxide material like phosphate and germanium, tellurite glasses have some of the most significant benefits, such as excellent malleability, low processing temperature, and superior mechanical strength [1]. Tellurite glass is useful in laser technology because of its many good qualities, including high transparency, large dielectric constant, large refractive index, a lower melting point, and remarkable nonlinear optical properties.…”

Nanomaterials based on graphene have outstanding properties, particularly in terms of optical performance. Using melt-quenching and low-cost spray coating procedures, we effectively generated a series of reduced graphene oxide-coated tellurite glasses doped with neodymium nanoparticles, denoted as rGO-ZBTNd (NPs) glasses. An X-ray diffraction study of glass samples validated the glass system's amorphous structure. FESEM morphological analysis was used to evaluate the appearance of rGO on the glass substrate and revealed the dispersion of rGO. UV-Vis spectroscopy was used to determine different absorption bands. The refractive index value calculated using the Dimitrov and Sakka equation was found to be more than n > 2.000 and in the range of 2.339 to 2.657 when compared to uncoated samples. On the basis of these findings, a new method involving rGO deposited on tellurite glass has been developed to improve the tellurite glass currently utilised in laser applications.
