The importance of substrates for the visibility of "dark" plasmonic modes
Saskia Fiedler, Søren Raza, Ruoqi Ai +5
Dark plasmonic modes have interesting properties, such as a longer lifetime and a narrower linewidth than their radiative counterpart, as well as little to no radiative losses. How…
Enhancement of the UV emission from gold/ZnO nanorods exhibiting no green luminescence
Saskia Fiedler, Laurent O. Lee Cheong Lem, Cuong Ton-That +2
Large reflection losses at interfaces in light emitting semiconductor devices cause a significant reduction in their light emission and energy efficiencies. Metal nanoparticle (NP)…
The role of surface depletion layer effects on the enhancement of the UV emission in ZnO induced by a nanostructured Al surface coating
Saskia Fiedler, Laurent O. Lee Cheong Lem, Cuong Ton-That +1
The UV enhancement of Al-coated ZnO single crystals with a wide range of carrier densities is systematically studied using depth-resolved cathodoluminescence (CL) and photoluminesc…
Correlative Study of Enhanced Excitonic Emission in ZnO Coated with Al Nanoparticles using Electron and Laser Excitation
Saskia Fiedler, Laurent O. Lee, Cheong Lem +4
Metal nanoparticle (NP) surface coatings are known to significantly enhance the ultra-violet luminescence intensity of ZnO. Although there is general agreement that resonantly exci…
