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.

有机液相环境强脉冲放电SiC纳米颗粒的制备及发光性能

以六甲基乙硅烷为有机液相环境，采用连续强脉冲放电法成功制备出颗粒分布相对均匀的SiC纳米颗粒。对样品进行了X射线衍射（XRD）、场发射扫描电子显微镜（FESEM）、透射电子显微镜（TEM）和拉曼光谱（Raman）测试。 XRD和拉曼数据表明颗粒成分主要由β-碳化硅。电子显微镜图像显示颗粒尺寸范围为 5-20 nm，并以团聚状态存在。进一步的光致发光（PL）结果表明，真空条件下的退火温度对发光强度具有显着的正向影响。
