Silicon Dioxide Layer Thickness-dependent Aunanocube@mSiO2@Ag with surface enhanced Raman scattering for Trace Detection of Harmful Substances

Aunanocube@mSiO2@Ag nanocomposites were synthesized by layer-by-layer assembly with Au nanocube core, Ag shell, and mesoporous silica as a spacer. The thickness of the mesoporous silica layer was controlled simply by...
