英文摘要	Nanocrystalline ge embedded in siox matrix is fabricated by oxidizing hydrogenated amorphous sice alloys or hydrogenated amorphous si/hydrogenated amorphous ge multilayers. the structures before and after oxidation are systematically investigated. visible light emission was observed from both samples. the luminescence peak is located at 2.2 ev which is independent of the starting materials. compared to the luminescence from unlayered samples, the photoluminescence spectrum from multilayered samples has a narrower band width, which can be attributed to the uniform size distribution. the light emission origin is also discussed briefly and a mechanism different from the quantum size effect is suggested.
