Abstract

Nanoconjugates composed of CdSe–ZnS core–shell nanocrystals and pyrenyl ligands are shown to exhibit a double photoluminescence. Owing to the different response of the two emission signals towards oxygen, the nanocrystals function as high dynamic range ratiometric luminescent O2 nanosensors.
