“Background Noble metal A-1210477 in vivo nanoparticles with strong localized surface plasmon resonances (LSPRs) have attracted great interests in fields such as nanoscale photonics, biological sensing, surface-enhanced Raman scattering (SERS), photocatalytic and photoelectron-chemical [1], plasmonic absorption enhancement of solar cell [2–10], nonlinear optics [11–14], and plasmon-enhanced fluorescence

ASK1 [15–22]. Localized plasmons are the collective oscillations of free electrons in metal nanoparticles. The LSPRs arising from the excitation of a collective electron oscillation within the metallic nanostructure induced by the incident light lead to enormous optical local-field enhancement and a dramatic wavelength selective photon scattering at the nanoscale [23–26]. Nanocomposites consisting of metal nanoparticles dispersed in a matrix of insulating materials such as polymers, ceramics, or glasses have recently received increased interest as advanced technological materials because of their unique physical properties. The optical properties of noble metal nanoparticles and their application in surface-enhanced photoluminescence are hot in the study of nanoscience. Recently, investigations of the surface enhancement effect on of the fluophor fluorescence have opened up a new methodology for modulating and improving optical properties. The effects of Ag nanoparticles on fluorescence properties of the dye molecules such as Rhodamine B and Nile blue were reported and observed for strong coupling of the particle plasmon resonance to the molecules. Rhodamine (R6G) is frequently used as one of the most efficient laser dyes characterized by a high-efficiency fluorescence band around 560 nm.
