New Publication

A recent JACS publication led by the Buonsanti group at EPFL reports the design of CdSe@AlOx quantum dot (QD)–dye nanocomposites that enable nearly distance-independent triplet energy transfer (TEnT) to polyaromatic hydrocarbon dyes, even across separations approaching 2 nm. This work highlights the ability of oxide shells to preserve QD optoelectronic properties while optimizing QD–dye interactions, opening new opportunities for light-harvesting, photon upconversion, and photocatalysis.
