Mixed metal–semiconductor nanocrystal aerogels, which are light-emitting and highly porous macroscopic monoliths, are fabricated. Thiol-stabilized CdTe and Au nanoparticles from aqueous synthesis act as building blocks. The content and the properties of the aerogels are tuned by variation of the initial CdTe to Au nanoparticle ratio. Materials of this type combining the optical and catalytic properties of their nanoscale building blocks with very high porosity of the gel structure are of special interest for applications in nanosensing and photocatalysis.
