However, hollow nanoparticles typically take on the shape of the template, of which few types exist. In this study, a galvanic replacement reaction was used to synthesize hollow gold nanocubes on solid silver nanocubes, which served as the template. Conventionally, galvanic replacement reactions were only suitable to synthesize hollow gold nanoparticles with the same shape as the silver template particles. Here, ascorbic acid was introduced as a weak reducing agent to reduce the gold ions to gold atoms and cetyltrimethylammonium bromide (CTAB) as a surfactant to fabricate hollow gold nanotetrakaidecahedrons by epitaxially depositing gold atoms on the hollow gold nanocubes. The surfactant CTAB is selectively and preferentially adsorbed on the {110} and {100} facets of the hollow nanocubes because of their higher free energies than the {111} facet, which inhibits the growth of the {110} and {100} facets. Consequently, the {111} facet grew the fastest and eventually occupied the largest area, whereas the area of the {100} facets was slightly smaller, and the {110} facets disappeared during the formation of the hollow gold nanotetrakaidecahedrons. The calculated optical absorption spectra provided further evidence for the mechanism of formation and growth of the hollow gold nanotetrakaidecahedrons. This indicates that by adjusting the experimental conditions, hollow nanoparticles with the desired shapes can be fabricated by subsequent oriented and epitaxial growth on the surfaces of hollow nanoparticles synthesized by the galvanic replacement reaction.</p></div>","PeriodicalId":736,"journal":{"name":"Plasmonics","volume":"18 5","pages":"1659 - 1665"},"PeriodicalIF":3.0,"publicationDate":"2023-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41229261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The principle of conventional SIRs is discussed in terms of equivalent circuit model and characteristic impedance. Among the three proposed plasmonic filters, one of them acts as a short-wavelength, while the other two nanostructures work as long-wavelength cut-off filters at near-infrared region (NIR) and telecom wavelengths.
