Thin films of neodymium (Nd) doped zinc oxide (NZO) were coated onto glass substrates at 400 °C by nebulized spray pyrolysis using different doping weight percentage (wt%) of Nd. The prepared films were exhibited in hexagonal structure of polycrystalline nature along with (002) preferential orientation. Morphological properties and elemental compositions were performed by scanning electron microscopy and energy dispersive by X-ray, respectively. Tauc’s plot discovered the optical energy band gap of 3.17 eV for 5 wt% Nd doped NZO film. PL profiles depicted a solid green emission peak at around 680 nm at room temperature. Optical constants such as refractive indices, dielectric constants, carrier concentration and plasma frequency were evaluated for NZO through optical approximation route. Hall mobility and carrier concentrations were enhanced with rise of Nd doping wt%. A drastic change in the resistivity was observed due to incorporation of Nd dopant and it has evidently demonstrated in detail.
