Enhancement of the UV emission from gold/ZnO nanorods exhibiting no green luminescence

Fiedler, Saskia; Lee Cheong Lem, Olivier; Ton-That, Cuong; Hoffmann, Axel; Phillips, Matthew R


Large reflection losses at interfaces in light-emitting semiconductor devices cause a significant reduction in their light emission and energy efficiencies. Metal nanoparticle (NP) surface coatings have been demonstrated to increase the light extraction efficiency from planar high refractive index semiconductor surfaces. This emission enhancement in Au NP-coated ZnO is widely attributed to involvement of a green (∼ 2.5 eV) deep level ZnO defect exciting localized surface plasmons in the NPs. In...[Show more]
