Hot-carrier-mediated impact excitation of Er3+ ions in SiO2 sensitized by Si Nanocrystals

Past research has shown that indirect excitation of Er3+ ions in SiO2 solid-state matrix with Si nanocrystals can be achieved by different pathways. Here, we investigate the impact excitation mechanisms in detail by means of time-resolved photoluminescence spectroscopy. We explicitly demonstrate tha...
