Ultraviolet light-emitting materials and devices with high-efficiency are required for many applications. One promising way to enhance the ultraviolet luminescence efficiency is by incorporating plasmonic nanostructures. However, a large energy mismatch between plasmons light emitters greatly limits direct realization of enhancement. In this work, single Ga-doped ZnO microwire prepared large-sized Ag nanoparticle (the diameter
