Fully Sensitized Upconversion Nanoparticles as Efficient Catalysts for NIR‐Driven UV Photochemistry

Angewandte Chemie International Edition, EarlyView.
Engineered NaYbF4:Tm3+@NaYF4 nanoparticles, featuring a fully sensitized Yb3+ lattice and an optimized core–shell architecture, convert five 980 nm photons by sequential absorption into a single 345 nm ultraviolet (UV) photon. This unprecedented anti‐Stokes shift enables energy‐demanding [2 + 2] photocycloadditions under mild, near‐infrared (NIR ...
