An X-ray absorption spectroscopic investigation into the electronic and optical properties of silicon nanocrystals (Si-NCs) derived from the thermal processing of hydrogen silsesquioxane (HSQ) is presented. Hydrofluoric (HF) acid etching and subsequent photochemical hydrosilylation with styrene liberates the as-synthesized oxide-embedded Si-NCs from their matrix and renders them solution dispersible...
