Abstract:   (359 Views)
Absorption and fluorescence spectra of Rhodamine B dye in the absence and presence of gold, silver and copper nanoparticles, are investigated. Because of the spectral overlapping of gold nanoparticles’ absorption and dye’s fluorescence, energy transfer from dye to nanoparticles has occurred and fluorescence of dye-gold nanoparticles mixture as compared with dye alone, is quenched. However, silver and copper nanoparticles caused by fluorescence enhancement of dye. Higher enhancement of the fluorescence intensity of Rhodamine B dye in the proximity of silver nanoparticles respects to copper nanoparticles due to the higher spectral overlapping of dye’s and silver nanoparticles’ absorption.
Keywords: Laser Ablation, Rhodamine B Dye, Gold Nanoparticles, Silver Nanoparticles and copper Nanoparticles
