Abstract

Optical detection of small single silicon nanocrystals is reported for crystals embedded in various environments. It is found that an external dielectric material has considerable influence on the photoluminescence (PL) properties of optically active states localized in the SiO₂ shell. The PL is controlled by two interfaces, namely the Si/SiO₂ and SiO₂/matrix interfaces. The electron-phonon interaction, as well as the electronic stabilization energy, is controlled by these interfaces. A simple model is derived that can qualitatively describe the effect of the different embedding matrices on the electron-phonon coupling.
