Si nanocrystals (Si-ncs) embedded in SiO 2 /SiN x multilayer structures can be of interest for optoelectronic devices such as solar cells. However, controlling the size and density of the Si-ncs is strongly requested for an efficient use in a functioning solar cell device. In this work, SiO 2 and S
## 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
