摘要：

A model is presented which explains the high degree of linear polarization of luminescence which was observed in porous silicon under non-resonant excitation. Porous silicon is supposed to be composed of elongated nanocrystals. We show that because of the anisotropy of the depolarizing field in silicon needles polarized light excites preferentially those nanocrystals which emit light with the same polarization
