Abstract

We report structural and vibrational properties of Mg doped ZnO nanoparticles. Structural studies are performed by X-ray diffraction technique, confirms that the prepared particles are in hexagonal wurtzite structure and the lattice parameters changes considerably due to doping. Vibrational properties done with Fourier Transform Infrared red spectroscopy (FTIR) show a band centered at 427cm^-1 corresponds to E₁(TO) mode. It is also observed that the intensity decreases with the increase of Mg concentration, apart from that the surface phonon modes are appeared at 460 and 521cm^-1. Compare to the undoped sample all the normal modes show red shift.
