摘要：

Time-resolved luminescence spectra of porous Si were measured under an N2 laser excitation. The luminescence shows a nonexponential decay with an initial time constant of less than 5 ns and more than 200 ns for the secondary decay. The luminescence is considered to be associated with localized states, which are probably conduction and valence sublevels in Si microstructures.
