We report improved efficiency of a phosphor (Lu3Al5O12: Ce3+) by exploiting the plasmonic effect of silver nanoparticles (Ag NPs) for white light-emitting diodes (WLEDs). In a position close to the Ag NPs, the phosphor leads to higher quantum efficiency. Ag NPs are synthesized in various shapes for different spectral overlaps, and coated with a dielectric material to enhance the localized surface plasmon resonance. We present a new method that can improve the efficiency of WLEDs at appropriate concentrations of Ag NPs
