A systematic investigation on the synthesis, characterization, optical and magnetic properties of (Co-Mn) co doped ZnO nanoparticles synthesized by sol-gel method is reported. Structural, Optical and magnetic properties of present sample have been characterized by X-ray diffraction (XRD), UV-VIS-NIR spectroscopy and VSM techniques. The single- phased wurtzite structure has been confirmed by XRD analysis. The nanoparticles nature of the samples and their crystallinity has been investigated by TEM measurements. Optical studies revealed red shift (3.315–3.289 eV) with increasing Mn doping concentration in the absorbance spectrum. Magnetization studies showed that Zn0.7Co0.2Mn0.1O exhibits ferromagnetic behavior.
