Figure S1. SEM images of (A) core-shell Ag@SiO2 and (B) Ag@SiO2 @mSiO2, (C) yolkshell Ag@mSiO2 and (D) Ag@mSiO2-100H (after hydrothermal treatment). The inset is the corresponding FESEM images with the scale of 50 nm.

Figure S2. TEM images of (A) core-shell Ag@SiO2 and (B) Ag@SiO2 @mSiO2, (C) yolk-shell Ag@mSiO2 and (D) Ag@mSiO2-100H (after hydrothermal treatment). All scales are 50 nm.
Figure S3. Small-angle X-ray scattering (SAXS) pattern of (a) core-shell Ag@SiO2 @mSiO2, (b) yolk-shell Ag@mSiO2 and (c) Ag@mSiO2-100H (after hydrothermal treatment). Table S1. Physicochemical properties of Ag@SiO2@mSiO2, yolk-shell Ag@mSiO2 (b) and Ag@mSiO2-100H (after hydrothermal treatment).

Figure S4. UV/Vis spectra of (a) Ag nanoparticles, (b) Ag@SiO2, (c) Ag@SiO2 @mSiO2, (d) yolk-shell Ag@mSiO2 and (e) Ag@mSiO2-100H. The corresponding SPR peaks were centered at 415, 450, 462, 450 and 450 nm, respectively.
Figure S5. Fourier transform infrared (FTIR) spectra of (a) as-made yolk-shell Ag@mSiO2100H/CTAB and (b) yolk-shell Ag@mSiO2-100H after the NH4NO3/ethanol solution extraction for twice. The strong absorption bands around 2920 cm-1 and 2849 cm-1 were assigned the stretching of the C–H bonds of the CTAB molecules. No FTIR adsorption peaks can be observed in the range of 2840-2950 cm-1 for yolk-shell Ag@mSiO2-100H, indicating that the CTAB molecules are completely removed.
Figure S6. X-Ray diffraction (XRD) patterns of the (a) yolk-shell Ag@mSiO2-100H (after hydrothermal treatment) and (b) Au-Ag@mSiO2 (synthesized with 1.0 mL of 0.5 mM HAuCl4 solution).
