## Abstract We present a photoluminescence excitation study of silicon nanocrystals in a SiO~2~ matrix. We show that although the excitation crossβsection is wavelengthβdependent and increases for shorter excitation wavelengths, the maximum timeβintegrated photoluminescence signal for a given sampl
