Abstract

Core-Shell (Fe 3 O 4 /Au) nanoparticles were synthesized using iron II chloride tetrahydrate (FeCl 2 H 2 O) and potassium tetrachloroaurate III (AuCl 4 K) precursors under microwave-assisted conditions. Products were analyzed using field emission gun electron microscope in transmission and scanning modes; energy disperse X-ray spectroscopy performed during STEM measurements indicated a signal for gold K and M signals at 9 keV and 13 keV, respectively, confirming Au atoms at nanoparticle's perimeter and Fe- L signal at 8 keV to be at the center.
