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