Abstract

We have carried out various spectroscopic studies of nn-butyl-passivated Si nanoparticles synthesized by solution routes. The photoluminescence (PL) spectrum of nn-butyl-passivated Si nanoparticles with mean diameter less than about 2 nm exhibits a strong emission around 3.3 eV photon energy. PL excitation (PLE) spectrum exhibits a distinct resonance around 4 eV in photon energy. Furthermore, we have carried out the valence-band photoemission measurements using synchrotron radiation in order to directly investigate their electronic structures in the vicinity of the Fermi level. From these results, the detailed optical properties and electronic structures of nn-butyl-passivated Si nanoparticles are discussed.
