Journal ArticleDOI
Quantum confinement in size-selected, surface-oxidized silicon nanocrystals.
TL;DR: Size-selective precipitation and size-exclusion chromatography cleanly separate the silicon nanocrystals from larger crystallites and aggregates and provide direct evidence for quantum confinement in luminescence.
Journal ArticleDOI

TL;DR: Near-edge and extended x-ray-absorption fine-structure measurements from a wide variety of oxidized Si nanocrystals and H-passivated porous Si samples, combined with electron microscopy, ir absorption, forward recoil scattering, and luminescence emission data, provide a consistent structural picture of the species responsible for the Luminescence observed in these systems.
Journal ArticleDOI
Electronic spectroscopy and photophysics of Si nanocrystals. Relationship to bulk c-Si and porous Si
TL;DR: In this paper, the structural characterization, electronic spectroscopy, and excited-state dynamics of surface-oxidized Si nanocrystals, prepared in a high-temperature aerosol apparatus, are studied to gain insight into the emission mechanism of visible light from these systems.
