摘要：

Measurements of the optical and structural characteristics of various porous Si samples have been correlated. Although the photoluminescence peak wavelength shows no correlation with the Si nanoparticle size, the optical absorption edge exhibits a strong inverse correlation that is in excellent agreement with theoretical predictions for the optical gap in Si spheres or quantum dots. This constitutes direct evidence for quantum confinement effects in porous Si.
