Series of glass 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 Nd ³⁺ ions exhibit emission transition of ²P₃/₂→⁴I9/₂, ⁴G7/₂→⁴I9/₂, ² H11/₂→⁴I9/₂, and ⁴F9/₂→⁴F9/₂ under 765 nm excitation wavelengths.
