Energy up‐conversion is the process by which two absorbed photons are converted in one photon of higher energy. Such a process can be conveniently performed by low‐power excitation through sensitized triplet–triplet annihilation and it is now an emerging technique with possible applications in different fields, including photovoltaic devices and bioimaging.
