摘　　要：首次发现ＳｉＣ纳米粉的光致发光效应，通过透射电镜、选区电子衍射、Ｘ射线衍射、高分辨电子显微镜和化学分析。Abstract The blue and violet emission of SiC nanometer powder was found. The photoluminescent mechanism was analysed by means of transmission electron microscope, selected area electron diffraction, X ray diffraction, fourier transform infrared spectroscope, high resolution electron microscope and chemical analyses. The results suggest that the quantum confinement effect of nanometer particles and microcrystalline be respectively responsible for the blue and light emission of SiC nanometer powder.
