Abstract

Ag nanoparticles (Ag-NPs) were adsorbed onto the surface of phosphor NaYFPO4:Dy3+ through an in situ reduction. The structure, morphology, composition, and optical properties were confirmed by X-ray diffraction, high-resolution transmission electron microscopy, energy-dispersive X-ray spectroscopy, and photoluminescence spectroscopy, respectively. The excitation peaks slightly shifted to long waves in the presence of Ag-NPs. Emission intensity increased by 115% owing to the enhancement of the local electromagnetic field near Ag-NPs because of the localized surface plasmon resonance. All these results indicated that the sample was a promising candidate for white LED devices.
