Step change in upconversion the key to clean water, green energy & futuristic medicine
"Upconversion: gluing (triplet-triplet annihilation) 2 low-energy photons together creates more energetic, visible light... key stage in upconversion achieved in solid state, likely enabling commercial scale... photon generation quantum yield 9.4%... solid state potentially using gel-like substance... upconverting into UV or from IR, hydrogen catalysis, solar energy (raise efficiency limit from 33.7 to 40+%), water purification (upconvert to harsh UV), night vision, 3D printing, treat tumors or create medicines with laser precision"
