Multicolored highly fluorescent silicon nanowires show potential in optoelectronic and biological applications because of their excellent aqueous dispersibility, strong photoluminescence, and high photostability.

The synthesis of fluorescent silicon nanowires by a one-pot, microwave-assisted strategy (see figure a) has been reported by collaborators from Soochow University and the City University of Hong Kong, both in China. These nanowires are decorated with red-, yellow, or green-emitting quantum dots (QDs), which makes them highly fluorescent (see figure b). The nanowires show excellent aqueous dispersibility, strong photoluminescence (quantum yield of ca. 30–35 %), and high photostability which are all important properties for long-term and real-time cellular imaging applications.
