We carefully evaluate how porous silicon (pSi) surface oxidation by ozone (O3) and the resulting changes in nanocrystallite surface chemistries (e.g., SiOSi, SiHx (x = 1-3), OySiH (y = 1-2), and SiOH) influence the pSi photoluminescence (PL). We discover a relationship between the pSi PL and the O2SiH band amplitude.
