ABSTRACT. Co doped ZnSe nano crystalline powder samples were prepared by solid-state reaction method.Structural, optical and magnetic properties of pure and Co doped ZnSe powders were studied. Both Pure and doped ZnSe samples were in cubic structure. Lattice parameter and band gap of pure and doped ZnSe powders decreased with increase of Co concentration. The Raman shift in the Raman spectra of the samples confirms the Co doping in to the ZnSe lattice.Band gap of the samples decreased with increase of Co concentration. Codoped ZnSepowders exhibited half-metallic ferromagnetism at room temperature with low Co concentration and paramagnetism with high Co concentration.
