Synthesis and Characterization of SERS-active silica-coated Au/Ag core/shell nanocubes
Research Mentor(s)
Dr. Ying Bao
Description
Noble metal nanomaterials have been intensively studied in nanotechnology for numerous applications in various fields. Bimetallic nanomaterials exhibit unique physical and optical properties that are inaccessible in comparable monometallic systems. In our work, a seed-mediated growth was used to form Ag nanocubes, the size of which could be controlled by the synthesis conditions. Furthermore, an additional shell layer consisting of organosilica was grown around the bimetallic nanocubes, and their effect on the SERS performance of the nanomaterials evaluated. A series of characterization methods were used to obtain valuable information concerning the nanostructures' morphology and SERS behaviors. In addition, the growth behavior of the silica layer on the nanostructures will be presented.
