AbstractThe enhancement of white light emission from quantum-dot-coated InGaN light-emitting diodes (LEDs) via localized surface plasmon (LSP) resonance of metallic nanoparticles (MNPs) is investigated and demonstrated. With liquid-immersion laser ablation of metals, MNPs with a broad range of dimensions were synthesized in a single process. Since the LSP resonant wavelength depends strongly on the dimensions of MNPs, enhancement over a wide range of wavelengths in the visible spectrum is expected. MNPs of Ag, Au, Cu, Ni and Ti were experimented on. It is found that all MNPs result in an increase in the luminous flux and luminous efficacy of the quantum-dot-coated LEDs, with Ag NPs having the strongest effect (17.9%) amongst all metals tested. This observation is explained in terms of the resonance of the polarizability of the MNPs. © 2011 IOP Publishing Ltd.
