Luminescent CdSe quantum dots 2.5 and 6.0 nm in diameter can be incorporated into low‐density silica aerogel matrices. In work reported by Stiegmann and co‐workers on p. 1965, aerogels are formed from the supercritical CO 2 extraction of an alcogel containing quantum dots surface passivated with 3‐aminopropyltriethoxysilane. The resulting aerogels, shown on the cover, are low scattering and display intense, stable luminescence.
