Establishment of Fluorescence Sensitization Method for Hydroxysafflor Yellow A

Figure 4

(a) Absorption spectra and (b) fluorescence spectra of HSYA in glycerol-water mixed solvents with an increasing volume fraction (0∼50%) of glycerol (f_w,Gl). (c) Changes in maximum fluorescence intensity of HSYA with f_w,Gl in glycerol-water mixed solvents. All spectra were measured at room temperature, with excitation at 450 nm.
