    Abstract

    Here we show that a mixture of multi-walled carbon nanotubes (MWCNTs) and ferrocene doped with sodium perchlorate, as an oxidant, can be combusted using a camera flash as an initiator. We optimize the MWCNT to oxidant ratio by monitoring the intensity and spectral characteristics of the light emission. In addition, we construct a novel nanostructured energetic material combining MWCNTs with porous silicon (pSi) impregnated with sodium perchlorate and show that pSi can be exploded using carbon nanotubes as photosensitive initiators.
