Study the Effect of Ag NWs Concentration on Surface Plasmon Polariton

The laser dyes can be used in many practical systems as a gain medium. The dye consists of fluorescence molecules in organic or water solvent. A dye can be pumped efficiently and can exhibit high gain, due to the high fluorescence quantum efficiency and broad emission and absorption cross-sections. For this reason, the dye used as a gain medium. The large bandwidth of the gain in the dyes gives a broad tuning range for the laser's output. It (RhB dye) was utilized at various concentrations, and a UV-VIS spectrometer was used to study the absorption spectra of these materials, followed by fluorescence spectroscopy to investigate the emission spectrum. A greater concentration of dye (1*10-5M) was used to mix with different amounts of Ag NWs. It will have a substantial influence on the parameters of the emission and absorption spectra. It was discovered that the emission parameters (emission intensity, lasing threshold) are greatly dependent on the concentration of Ag NWs.
