Solid-state material turns visible light into high-energy UV at sunlight intensity, expanding solar energy potential
Researchers at Kyushu University have developed a solid-state material capable of converting visible light into high-energy ultraviolet light. This process, known as photo upconversion, uses triplet-triplet annihilation to combine low-energy photons into a single higher-energy photon.
Why it matters
This technology could significantly improve the efficiency of solar energy applications and industrial processes like 3D printing and air purification that rely on UV light.
