Abstract: (1692 Views)
In recent years, combing the optical properties of plasmonic nanoparticles (gold or silver) with magnetic properties of iron oxide nanoparticles in the form of core/shell has gained scientists’ attention. This combination decreases the toxicity of iron oxide nanoparticles and increases their stability and their applications and properties can be improved by changing the thickness of the shell. In this paper, first iron oxide nanoparticles were synthesized by co-precipitation method. Then by using pulsed laser ablation method, iron oxide nanoparticles were coated by gold. After synthesis iron oxide-gold core/shell nanoparticles were washed by magnetic separation to eliminate the gold nanoparticles. we used FE-SEM, UV-Visible and Fourier transform infrared spectroscopy for characterization. The spectroscopies confirmed the coating of iron oxide nanoparticles with gold.
