Abstract

Discrepancies exists regarding the nature of photoluminescence from quantum-confined silicon nanocrystals. Here, using hydrostatic pressure, x-ray diffraction, and optical spectroscopy, we provide fundamental insights regarding whether emission arises from nanocrystal surface or core states.
