Amorphous Silicon Nanoparticles

ABSTRACTA method for synthesizing crystalline and/or amorphous silicon nanoparticles (3 – 30 nm diameter) is discussed. The photoluminescence (PL) behaviour of these particles is studied as crystallinity, size, surface stoichiometry, and excitation frequency are varied. Orange-red photoluminescence (PL), similar to that reported for “porous silicon,” is observed. The wavelength dependence of this PL is not a function of size, but rather particle crystallinity. A separate PL feature, near 430 nm, is reported. No size dependent effects are observed for this feature.

ABSTRACTThe reactivity of silicon nanocrystals (Si-NCs) in near-UV photochemical hydrosilylation was evaluated as a function of size. Results show that Si-NCs with photoluminescence (PL) in the visible spectral region react faster than Si-NCs with near-IR PL. Fourier-transform infrared (FTIR) spectroscopy suggests this difference in reactivity is due to quantum size effects in the exciton-mediated mechanism proposed for this reaction. We have carried out a detailed comparison of Si-NC reactivity in photochemical and thermal hydrosilylation and determined the conditions under which Si-NCs may be size-selected based on their reactivity.
