Leveraging on plasmonic hot electrons is an emerging strategy for electron–hole separation towards efficient photovoltaics and photocatalysis. On page 960, X. Huang, S. J. Wang, S. J. Chua, and co-workers extend this concept to electron–hole recombination for illumination, which is rarely reported. By taking advantage of the good energy match between the dopant-correlated green luminescence in Cu-doped ZnO nanowires and the localized surface plasmon resonance of Au nanoparticles, an intense, ultrafast, and temperature-robust UV luminescence is achieved in the nanowires after coating with Au nanoparticles.
