Abstract
A novel synthesis route towards silicon carbide whiskers with hexagonal cross-section from the precursor of hydrogen-silicone oil-divinylbenzene (H-PSO-DVB) has been firstly reported. The phase, chemical bonds and structure of the whiskers were correspondingly analyzed. The SiC whiskers with high purity show a layered structure and a gradual increase in the cross-section size. In view of the presence of Fe catalytic ball at the tips, a possible vapor-liquid-solid mechanism was used to explain the growth process of these whiskers. Photoluminescence characterization of the SiC whisker displays a strong blue emission at 440 nm, indicating its potential and favorable application as a nano-optical device.
