Abstract

New water-soluble silicon quantum dots (Si QDs) with substantial photoluminescence (PL) in the visible region are simply prepared in one-pot synthesis at room temperature for biomedical applications. Hydroxide-capped Si QDs are water-soluble and their PL characteristics were investigated by PL spectroscopy. The water-soluble Si QDs emit the PL at 470 nm with a full width at half maximum height (FWHM) of 90 nm. Absolute quantum yields were measured and were 6%. The integrated PL as a function of time for the water-soluble Si QDs indicates that the PL of water-soluble Si QDs are stable.
