Tellurium oxide-based glasses have a lot of interests due to their specific physical and chemical properties such as high refractive index, wide band infrared transmittance and large third order non-linear optical susceptibility. This work is focused on 80TeO₂-xZnO-(20-x)Na₂O (TZN) ternary glassy system doped with Nd³⁺ ion and without doping. This oral presentation will correlate the evolution of the correlation length given from a boson peak in Raman spectra (called here Blob size) and the results from XAFS experiment to show the influence of Nd³⁺ ions doping on the TZN network, which shows a total difference in evolution with an increase of the ZnO concentration (overall decrease of the blob size when doped compared to an increase when non-doped).
