| 中文摘要 | nanocrystalline ge embedded in amorphous silicon dioxide matrix was fabricated by oxidizing hydrogenated amorphous si/hydrogenated amorphous ge (a-si:h/a-ge:h) multilayers. the structures before and after oxidation were systematically investigated. the orange-green light emission was observed at room temperature and the luminescence peak was located at 2.2 ev. the size dependence in the photoluminescence peak energy was not observed and the luminescence intensity was increased gradually with oxidation time. the origin for this visible light emission is discussed. in contrast to the simple quantum effect model, the surface defect states of nanocrystalline ge are believed to play an important role in radiative recombination process.
