Abstract
The present disclosure features photon upconversion systems, including a sensitizer and an emitter, wherein the sensitizer absorbs an energy from an incident radiation, and the emitter accepts the energy from the sensitizer via triplet-triplet energy transfer, and emits at a lower wavelength than the incident radiation via a triplet-triplet annihilation process. The present disclosure also features devices including the photon upconversion systems.
