The morphology of Au‐decorated ZnO nanorods and the two‐photon excitation process of this as‐prepared composite material are explored by C. X. Xu and co‐workers. As demonstrated on page 940, the two‐photon excited UV emission of Au‐decorated ZnO can be significantly enhanced under an excitation of 520 nm, consistent with the localized surface plasmon resonance (LSPR) peak of Au nanoparticles (NPs). This improvement is attributed to the strong local field enhancement generated by the LSPR of the NPs.
