Zn-ZnO Core-Shell Nanoparticles: Numerical Simulations and Experimental Realization

Abstract

Zinc nanoparticles ensembles on quartz supports have been fabricated via laser ablation and physical vapor deposition. A red-shift of the plasmon bands relative to the computed values for the isolated semispherical nanoparticles has been observed. After annealing in air zinc nanoparticles turn into zinc oxide nanoparticles suitable for investigation of their luminescent and sensor properties.
