Surface plasmon (SP) mediated near band-edge emission in Ag/ZnO nanorods has been systematically studied by using a temperature-dependent photoluminescence spectra technique. It was found that the mediation mainly concerns SP couplings with two emissions, one from neutral donor-bound exciton D 0 X recombination and another from the radiative transition of free electron to neutral acceptor (e, A 0). The first coupling process is demonstrated to prevail in the temperature range from 300 to 150 K, while the second is dominant below 150 K. The competition mechanism and the role of exciton and carrier delocalizations in the coupling processes have been explored in the unique Ag/ZnO nanostructures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
