摘要：

By exploiting a simple solution approach, we bound ethoxy-terminated Si nanoparticles to surface functionalized multi-walled carbon nanotubes (MWCNTs) via covalent bonds. Quenching of photoluminescence (PL) of the Si nanoparticles was observed once they were conjugated to the MWCNTs. Analysis of the time-resolved PL decay and calculation indicated that Foster resonance energy transfer from the Si nanoparticles to the MWCNTs may be responsible for the PL quenching. The results suggest novel potential applications of the unique Si/MWCNT nanocomposites in optoelectronic devices.
