(a) UV-IR extinction spectra of Ag@Au NPs in 6 different solvents: CH3OH (n = 1.3301), H2O (n = 1.333), CH3CN (n = 1.343), C2H5OH (n = 1.362), CH3(OH)CH3CH (n = 1.3776), and HOCH2CH2OH (n = 1.4318). (b) Relationship between the LSPR λmax shift of Ag@Au core-shell NPs and the refractive index (n) of the solvent.
