WebAs triplet-triplet annihilation combines the energy of two triplet excited molecules onto one molecule to produce a higher excited state it has been used to convert the energy of two photons into one photon of higher energy, a process known as photon upconversion. [6] [7] To achieve photon upconversion through triplet-triplet annihilation two ... WebMar 13, 2024 · We propose the use of an n-doped periodic AlN/GaN quantum cascade structure for the optical up-conversion of multiple near-infrared (near-IR) photons into deep-ultraviolet (deep-UV) radiation. Without applying an external bias voltage, the active region of such a device will (similar to an un-biased quantum cascade laser) resemble a sawtooth … WebApr 12, 2024 · Here, we propose and experimentally realize a photon-recycling incandescent lighting device (PRILD) with a luminous efficacy of 173.6 lumens per watt (efficiency of … butchers clayton bradford
