Semiconductor nanocrystals (NCs) hold great promise as sensitizers for triplet-triplet annihilation up-conversion (TTA-UC) due to their facile bandgap tunability and negligible inter-system crossing ...

Harvesting this light more efficiently is possible thanks to a process called photon energy upconversion where two or more weak captured photons are converted into a single strong, energy-rich photon.
