Abstract: Zinc oxide with neodymium ions nanomaterials were synthesized by using the chemical synthesis method. The materials were characterized by XRD, FTIR, TEM, SEM and spectral analysis. From XRD, TEM and SEM images, the estimated average particle size are 20, 100 and 200nm respectively. Nearly hexagonal shapes for the dark spots in the TEM images indicate that the ZnO nanoparticles are almost hexagonal. SEM demonstrates clearly the formation of cluster type of ZnO nanoparticles and change of the morphology of the nanoparticles with the Nd3+ different ions concentration. UV- Visible absorption spectrum of the ZnO:Nd3+ nanomaterial was analyzed on the basis of Judd-Ofelt (J-O) theory. Nine absorption and four fluorescence bands have been observed at room temperature. Energy interaction and intensity parameters have been computed Fluorescence band have been assigned to transitions 4F3/2 → 4I9/2, 4F3/2 →4I11/2, 4F3/2 →4I13/2, and 4F3/2 →4I15/2. The radiative properties were computed using the J-O intensity parameters and fluorescence data. The value of emission cross-section is an important parameter and signifies the rate of energy extraction from the optical material.
