摘要：
Porous beta-SiC has been formed by C+ implantation into crystal Si followed by thermal annealing and anodization. The photoluminescence was measured. The microstructures were observed by cross-sectional and planar electron transmission microscope (TEM) and high resolution TEM. The growth of SiC precipitates and the formation of porous SiC are discussed. On the basis of microstructure analysis, the intense blue emission from porous beta-SiC is explained by the quantum confinement effect.
