Abstract

In this study, the effect of types and concentrations of nanoparticles on the performance of plasmonic active media has been addressed, especially the intensity of their emission spectra, and the effect of the three different dye concentrations and the concentration of the Au NPs and Ag NPs were studied, separately, and it appeared through the experiment that the appropriate concentration of the dye must be chosen for each specific range of the concentrations of the Au NPs and Ag NPs. and it was found through the study that adding different concentrations of nanoparticles improves the plasmonic in the active media.In this study, the effect of types and concentrations of nanoparticles on the performance of plasmonic active media has been addressed, especially the intensity of their emission spectra, and the effect of the three different dye concentrations and the concentration of the Au NPs and Ag NPs were studied, separately, and it appeared through the experiment that the appropriate concentration of the dye must be chosen for each specific range of the concentrations of the Au NPs and Ag NPs. and it was found through the study that adding different concentrations of nanoparticles improves the plasmonic in the active media.
