Description	We present the optical absorption spectra of metal nanoparticles prepared by thermal annealing of the ultra thin metal films evaporated on polycrystalline ZnO films. The surface morphology, particle size and density were monitored by the atomic force microscopy (AFM) and scanning electron microscopy (SEM). The optical absorptance spectra of gold nanoparticles embedded in the non-absorbing medium can be simulated by effective medium approximation-EMA (Maxwell-Garnett model). The maximum of the localized plasmon resonance shifts to longer wavelengths (red shift) when the metal nanoparticles are more tightly packed in the matrix, whereas the size of the nanoparticles determinate the width of the resonance peak. The electron scattering cross section of Au nanoparticles observed by SEM is about two times larger than their diameter.
