Doing photon upconversion a solid—Crystals that convert light to more useful wavelengths – EurekAlert
Solid-solution organic crystals have been brought into the quest for superior photon upconversion materials, which transform…

image: The sensitizer molecules (green) absorb low energy photons (long-wavelength light) and become excited into triplet states. These triplet states are then transferred to nearby annihilator molecules (blue), which then pass them around throughout the…
