Time-resolved photoluminescence spectroscopy of the initial oxidation

Original language description

In this paper we study the influence of progressing oxidation on the photoluminescence spectra of small silicon nanocrystals (SiNCs). H-terminated SiNCs exhibit only a fast approximately nanosecond photoluminescence component at about 525 nm, quenched and redshifted to about 550 nm by progressing oxidation. At the same time a new approximately microsecond photoluminescence component appears, intensity of which progressively increases and its peak position redshifts continuously from 575 up to 660 nm. Weinterpret our observations in terms of the quasidirect core electron-hole pair recombination quenched by the ultrafast trapping into the oxygen-related surface/interface states, forming within the band gap due to oxidation.
