Abstract :
Fe and Co co-doped ZnO nanoparticles were synthesized by hydrothermal method. Limit of substitution was identified using XRD. Magnetic measurements at room temperature for doped samples showed paramagnetic and ferromagnetic in nature. The reflectance spectra exhibited the absorption peaks corresponding to both dopant and host ions. Emission spectra show defect related peaks, suppression of visible spectra peaks is observed in doped samples.
