Series of glasses based on (75-x)TeO2-15MgO-10Na2O-xNd2O3, where x=0, 1.0, 2.0 and 3.0, are synthesized by conventional melt-quenching technique. The nanoglass particles are derived from heat treatment of this glass near crystallisation temperature for 3 hours. The existence of nanocrystalline nature of this glass is confirmed by x-ray diffraction (XRD) technique followed by calculation using Scherrer equation. Meanwhile, the crystallization temperature, Tc determined using Differential thermal analysis (DTA). The fluorescence spectra of Nd3+ions exhibit emission transition of2P3/24I9/2,4G7/24I9/2,2H11/24I9/2, and4F9/24I9/2under 765 nm excitation wavelengths.
