(Nanowerk News) Solar cell technologies have been improving incrementally over the decades, but energy conversion has remained less than optimal. Now, researchers at Kyoto University have developed a ...

Photon upconversion (UC) is a process in which a material increases the energy of incident photons, resulting in the emission of photons with higher energies. The potential applications of UC include ...

Electron transfer is enhanced by minimal energetic driving force at the organic-semiconductor interface in upconversion (UC) organic light emitting diodes (OLEDs), resulting in efficient blue UC-OLEDs ...

Upconversion nanoparticles are a new generation of fluorophore, relying on both physical and chemical principles to convert photons from a lower energy state to a higher energy state. It is common for ...
