Doing photon upconversion a solid — Crystals that convert light to more useful wavelengths

Solid-solution organic crystals have been brought into the quest for superior photon upconversion materials, which transform presently wasted long-wavelength light into more useful shorter wavelength light. Scientists revisited a materials approach previously deemed lackluster -- using a molecule originally developed for organic LEDs -- achieving outstanding performance and efficiency. Their findings pave the way for many novel photonic technologies, such as better solar cells and photocatalysts for hydrogen and hydrocarbon productions.
