WebbN2 - We develop an easy and effective pathway to improve surface-enhanced Raman scattering (SERS) effects of probe molecules of Rhodamine 6G (R6G) adsorbed on electrochemically prepared roughened Ag substrates. In general SERS studies, SERS-active metal substrates are first prepared. Webbför 2 dagar sedan · Compared with sapphire, we found that using GaN as a substrate for WS 2 can effectively enhance the SERS signal, with an enhancement factor of 6.45 × 10 …
WebbThe present paper focused on the synthesis and Hg(II)-sensing behavior of two rhodamine derived probes. Up-conversion NaYF 4 nanocrystals were constructed and applied as the excitation host so that those probes could be lightened by the 980 nm excited up-conversion emission, aiming at better probe photostability. The efficient energy transfer … WebbThe tip-enhanced near-field Raman (TERS) bands of Rhodamine 6G (R6G), that we reported earlier [Chem. Phys. Lett. 2001, 335, 369.], are assigned on the basis of density …
WebbWe report the dynamic behavior of surface-enhancement Raman scattering (SERS) spectra using rhodamine 6G dye (R6G, 10–8 mol L–1) adsorbed on gold nanorods (AuNRs). SERS spectra displayed a strong time-dependence intensity in wet to dry transition states. WebbRhodamine 6G (Rh6G) dye is tested comparatively for positively and negatively charged Au NPs prepared by the reduction of chitosan and citric acid, respectively. The adsorption of …
