Abstract

We demonstrate that a hybrid nanostructure consisting of a RuO₂ nanoparticle (NP)–ZnO nanorod confers dual local surface plasmon resonance (LSPR) enhancement of ultraviolet (UV) light emission and increase of visible light absorption. A RuO₂ NP–ZnO nanorod hybrid was fabricated by an atomic layer deposition method. The size and compositional control of the RuO₂ NP allowed (i) visible light absorption increase by the LSPR effect and (ii) proper interfacial electronic alignment of the RuO₂–ZnO nanojunction, leading to LSPR coupling with UV light emission enhancement. Based on the combined LSPR effect factor, the dual functionality of LSPR was maximized with 10–20 nm sized RuO₂ NPs. These results suggest that a sophisticated design of the nanostructure material heterointerface enables LSPR enhancement of both light harvesting and emission.
