研究了激光ＣＶＤ合成纳米硅（平均粒径为１４ｎｍ）的可见发光特性。用３００－４５０ｎｍ波长激发时，在４００－６５０ｎｍ区间观测到了发射宽峰。首次发现粒径大于１０ｎｍ的纳米硅在室温下具有可见发光，该现象可用量子限制／发光中心模型来作定性解释。
The visible luminescence properties of nanosized silicon (average particle size 14 nm) synthesized by laser CVD were studied. When excited with a wavelength of 300-450 nm, a broad emission peak was observed in the range of 400-650 nm. For the first time, it is found that nanosilica with a size of more than 10 nm has visible luminescence at room temperature, which can be qualitatively explained by a quantum confinement / luminescence center model.
