摘要：
The high-energy tail of the luminescence spectrum of porous Si excited with low photon energies has been observed to extend beyond the excitation energy. The temperature dependence of the luminescence intensity strongly depends on the excitation energy. These phenomena are explained in terms of phonon-assisted excitation of luminescence centers with strong phonon coupling.
