Enhancement of ZnO photoluminescence by laser nanostructuring of Ag underlayer

► The results of synthesis and characterization of Ag/ZnO nanocomposite heterostructures are presented. ► The size distribution of the Ag nanoparticles depends on the laser deposition and laser annealing procedures. ► The photoluminescent intensity of ZnO layers is strongly enhanced by plasmon absorption in Ag nanoparticles.
