【摘要】 测定了多孔硅的吸收光谱和反射光谱，结果发现其吸收边对应于可见光区域。同单晶硅相比，其吸收边发生了蓝移，并且吸收强烈。由多孔硅反射谱曲线，利用Ｋ－Ｋ关系对其光学常数进行了简单的计算和分析更多还原

【Abstract】 Optical absorption and reflection spectra of porous silicon (PS) are measured and analyzed,the result shows that the absorption edge of PS corresponds to the visible region.Compared with crystal silicon,porous silicon has a stronger optical absorption and blue shift has taken place at its absorption edge.Simple calculation and analysis of the optical constants of PS are made from the optical reflection spectrum curve by means of Kramers-Kroning relation.更多还原
