Fig. 2From: Surface-enhanced Raman scattering spectra revealing the inter-cultivar differences for Chinese ornamental Flos Chrysanthemum: a new promising method for plant taxonomyThe tentative relationship between the laser excitation power and SERS spectra. a The SERS spectral intensity goes with the laser excitation power (for instance of the Blue Eye cultivar, 785 nm excitation). b The growing trends of intensities for individual peaks might be related to the laser excitation power (for instance of the Blue Eye cultivar, 785 nm excitation)Back to article page
