摘要
多孔硅研究的新进展陈乾旺李新建朱警生周贵恩李晓光张裕恒（中国科学院中国科学技术大学结构分析开放研究实验室，合肥２３００２６）自１９９０年Ｃａｎｈａｍ发现多孔硅发射可见光的现象以来，人们对多孔硅的形成机理、发光机制和可能的技术上应用作了大量的工作。然而...
In this paper a critical review is presented for preparation microstructure and emission mechanism of porous silicon (PS).Among the various techniques employed to obtain PS, the emphasis is givenn on the hydrothermal erosion we recently invented. The microstructure was studied by STM,HREM,XRD and SAXS,which shows that there exists orderly dispersed silicon quantum dots covered by silicon oxide in PS.The three dimensional quantum confinement in silicon nanocrystallites (<3nm)was suggested to be related to the blue emission observed in PS.
