Abstract
SiC nanoparticles with relatively uniform particle distribution were successfully prepared using a continuous strong pulse discharge method using hexamethyldisilane as the organic liquid phase environment. The samples were subjected to x-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and Raman spectroscopy (Raman) tests. XRD and Raman data indicate that the particle composition is mainly composed of β-SiC. The electron microscope image illustrates particle sizes ranging from 5–20 nm and existing in an agglomerated state. Further photoluminescence (PL) results indicate that the annealing temperature under vacuum conditions has a significant positive effect on the luminescence intensity.
