| Popis: | In the present study, an application of Ag nanoparticles (AgNPs) in order to obtain Surface-enhanced Raman spectroscopy (SERS) of disperse dyes on single cotton fiber is presented. In detail, we prepared colloid Ag by use of citrate reduction method. Add one drop of the colloid on single colored fiber and then Raman spectra recorded with excitation wavelength at 785 nm were carried out on a Renishaw Raman spectrometer coupled to a 20x object lens. Cotton fibers dyed by disperse red 17 (DR17) and disperse blue 35 (DB35) are characterized and analyzed. This method was found out to be an effectively way to identify both DR17 and DB35 on single cotton fibers. Furthermore, SERS expands methods for identification disperse dyes on fibers, and provide a good method for verify colored cotton fibers. |
