Blue emission at NIR excitation : A strategy, based on energy management in nanostructured materials, is reported for photon upconversion of near‐infrared light. Several optical processes can be integrated into a single nanoparticle (see picture). The effect offers upconversion emissions spanning from ultraviolet to the visible spectral region by excitation at 808 nm.
