Abstract

β SiC nanoparticles and core shell nanoparticles were synthesized by sol gel and carbothermal reduction method s , in which corn and tetraethoxysilane (TEOS) were respectively employed as carbon and silica precursors, cobalt nitrate as additive. These particles were characterized by X ray diffraction, scanning electron micros cope, transmission electron microscope and photoluminescence. The results show that the β SiC nanoparticles and core shell nanoparticles with a diameter of 20 8 0 nm. A possible growth mechanism was proposed for the nanoparticles according to the characterization results. Th e synthesized nanoparticles exhibit different photoluminescence properties due to their core shell structure , quantum size confinement, core shell interface defects and internal structure defects..
