| titleOfInvention | Silver-mesoporous silica-silver sandwich core shell nanometer material and preparation and application thereof |
| abstract | The invention provides a stable silver-mesoporous silica-silver sandwich core shell nanometer material high in SERS activity. The core shell nanometer material is composed of an inner core, a middle layer and an outer shell. The inner core is silver nanometer particles with the practical size ranging from 10 micrometers to 90 micrometers. The middle layer is a mesoporous silica layer with the thickness ranging from 10 micrometers to 200 micrometers. The outer side of the middle layer is wrapped with the outer shell formed by the silver nanometer particles with the practical size ranging from 10 micrometers to 90 micrometers. The stable silver-mesoporous silica-silver sandwich core shell nanometer material is prepared from a hydrothermal reaction method, inner-layer precious metal silver nanometer particles and outer-layer precious metal silver nanometer particles are arranged, the surface local area electromagnetic fields generated by the precious metal silver nanometer particles can generate the coupling effect under the action of external exciting light, and an SERS signal with the extremely high intensity is generated and output. The preparation process is simple, short in period and high in yield is high, and the material is easy to popularize and suitable for mass production. |
