在氧气、空气或氮气环境中，用脉冲激光辐照加工出的纳米硅有较强的PL发光，将这些PL光谱进行高斯去卷积处理，可以得到不同的子峰，这是因为在氧气、空气或氮气中加工出的纳米硅能带带隙中有与氧和氮有关的局域态。结合计算结果，在纳米硅中Si=0双键和si—N键等可引入的局域态对PL发光有贡献。

There is a strong PL in silicon nanocrystals prepared by ns pulsed laser under the oxygen, air- gen. After Gaussian de-convolution of the PL spectra has been performed, different Gaussian peaks can be ob- tained, because there are Localized states related to oxygen and nitrogen in band gap of silicon nanocrystals pre- pared under oxygen, air or nitrogen. Combining with the calculation results, We found that localized states intro- duced by Si = 0 and Si-N in silicon nanocrystals make contributions to the PLemission.
