UV/Vis spectra of aqueous solutions of DFNS/Au dots and DFNS/Au nanohybrids synthesized using various HAuCl4(aq) concentrations: ii) 1.25 mm, iii) 2.5 mm, iv) 5 mm, v) 10 mm, vi) 20 mm, and vii) 30 mm HAuCl4(aq) (the same volume of the second growth solution, 0.8 mL, is used in all cases). According to the synthesis ratio (molar ratio=amount of HAuCl4 in the growth solution/ amount of HAuCl4 in the DFNS/Au dots), the reaction ratio can be assigned as: ii) 7, iii) 15, iv) 30, v) 61, vi) 123, and vii) 246.
