Abstract A system of zinc tellurite glasses with chemical composition [(TeO2)0.70 (ZnO)0.30]1-x (Nd2O3 NPs)x, where x ranged from 0.01 to 0.05 molar fraction have been prepared and coded as TZND have been fabricated using the melt-quenching technique. The aim was to study the structural, physical, and optical properties of the sample glasses. The choice of the chemical composition was to provide high refractive index, favourable metallization criterion and other optical qualities for linear and non-linear optical applications. The optical properties were studied using the UV–Vis spectroscopic analysis. The density and molar volume were found to increase with Nd2O3 NPs concentration. The FTIR spectral analysis showed the existence of TeO3 and T eO4 structural units which varying concentrations of T eO4 observed with N d2O3 nanoparticles (NPs). The transmission electron microscopy (TEM) analysis showed the agglomeration of the N d2O3 NPs in the morphological structure of the glasses. The variations of the optical parameters were mostly related to the variation in the structural nature of the glasses (TeO3 and TeO4 concentration changes). High refractive index value, ranging between 2.5470 and 2.6093, favourable metallization criterion value range of 0.3406 and 0.3535 as well as high polarizabilities and the optical basicity reveal that the glasses have high potential in optical fibre technology as well as optical non-linear (laser) applications.

Great attention is given to tellurite-based glasses over the few decades due to their specific properties and application [1, 2]. The glass science and technology has found so much interest in tellurite glasses over the year. This may be attributed to their low melting points, high dielectric constants and refractive indices, good infrared transmission and high rare earth solubility [3, 4]. Doping the glass with nanoparticles is of great interest, typically to study the effect of nanosize particles on optical behaviour of a glass material [5]. The recent application of tellurite glasses in the synthesis of metallic nanopartic
