Luminescent CdSe quantum dots of 2.5 and 6.0 nm dimension have been incorporated into a low‐density silica aerogels matrix. The aerogels are formed from the supercritical CO 2 extraction of an alcogel containing quantum dots surface passivated with 3‐aminopropyltriethoxysilane. The resulting aerogels (see figure and cover) are low scattering and show intense, stable luminescence.
