Quantum dots enabling all-in-one controllable polymerization through triplet energy transfer [PDF]

Nature Communications
Colloidal quantum dots (QDs) have recently emerged as a class of initiators or activators for photopolymerization, typically relying on photoinduced charge transfer from QDs to co-additives. Here we report efficient photopolymerization of acrylates using
