Abstract
Thin films LiNixMn2-xO4 (x=0, 0.4, 0.5, 0.6) were prepared by Sol-Gel method employing spin-coated technique. The films were annealed at 600°C for 2 hours. The structural properties of the films were studied by XRD technique. The films were found in cubic spinel structure with decreasing in the lattice constant by increasing the substitution ratio until x=0.5. After this ratio additional peaks appearing in XRD pattern, this indicates a phase transition of LiNi0.6Mn1.4O4 thin film. Optical properties of the LiNixMn2-xO4 thin films were investigated by UV–VIS spectroscopy in [400-900] nm rang. The study indicated the presence of a high absorbency values in some part of visible range spectrum of the LiNixMn2-xO4 thin films. Direct optical band gap for thin films LiNixMn2-xO4 were estimated.
