In this study a ternary system of TeO2‐ZnO‐Na2O (TZN) with competitive roles of covalent Zn‐O and ionic Na‐O bonds in tellurite glassy network were examined for high temperature in‐situ X‐ray diffraction (XRD) and Raman spectroscopy. TZN glasses were doped with Nd2O3 and the effects of Nd doping on the crystallization of glasses were also written....

In this study, the ternary system of TeO2–ZnO–Na2O (TZN) with a fixed TeO2 content of 80 mol. % and with a varied ZnO and Na2O content of totally 20 mol. % was examined for thermal/mechanical properties, Raman and x-ray absorption fine structure (XAFS) spectra, and the evolution of medium distance (correlation length) of order, called blob size her...

Thermal, mechanical structural, and optical properties of the 80TeO2-xZnO-(20-x)Na2O (TZN) system were investigated. The structural study of the glasses showed that in the TZN system, the zinc had a coordination and hence a behavior change in the tellurite matrix as a function of the concentration. Those results were correlated to the elastic prope...

In situ Raman spectroscopy, Resonance Frequency and Damping Analysis (RFDA) setup and Associated Raman Brillouin Calorimeter (ARABICA) setup experiments as a function of temperature were conducted on the (100-x)TeO2–5TiO2–xZnO (x = =15; 17.5; 20; 22.5; 25) glass system. Structural and mechanical properties showed non-conventional properties evoluti...

This paper describes Nd³⁺-ions doped multicomponent tellurite glasses TeO2-TiO2-ZnO (TTZ) applicable to advanced optical devices, which were characterized by UV–Vis-NIR absorption, Raman, and photoluminescence (PL) techniques. Not only did we perform experimental characterizations but also theoretically predicted the PL properties of Nd³⁺-doped TTZ...

Ce travail a pour but l’étude comparative de trois systèmes d’intérêt pour des applications en optique non linéaire, TeO2-TiO2-ZnO (TTZ), TeO2-TiO2-Nb2O5 (TTN) and TeO2-GeO2-ZnO (TGZ). L’objectif étant de mettre en évidence une corrélation entre la structure et les propriétés mécaniques de ces verres à température ambiante mais surtout en fonction...

The glass-forming domain, density, thermal, structural and optical properties of new glasses within the TeO2-NbO2.5-WO3 system have been investigated. By means of Raman spectroscopy, a thorough structural analysis of these glasses has been undertaken on the basis of a full-scale spectral decomposition process. The optical transmission window, refra...
