Optical Properties of Near-Infrared Cyanine Dye Molecules Adsorbed on Silver Nanoparticles
The optical property of near-infrared cyanine dye adsorbed on silver nanopaticals has been studied by means of UV-Vis spectrophotometer. The adsorption of near-IR cyanine dye on silver nanopaticles was highly dependent on the concentration of silver nanoparticles. As a result, in the UV-Vis spectra, it was shown that the “red-shift, as silver nanoparticles size, increased and the “blue-shift, as concentration of silver nanoparticle increased as well. The adsorbed spectral peaks of near-infrared cyanine dye disappeared as concentration of silver nanoparticles increased.
