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
The absorption and reflection spectra of the porous silicon were measured. As a result, it was found that the absorption edge corresponded to the visible light region. Compared with monocrystalline silicon, the absorption edge of the blue shift occurs, and strong absorption. Based on the reflection curve of porous silicon, the optical constants are simply calculated and analyzed by K-K
