摘要:	摘要： This article reports the preparation of silver-free Au nanocages from cubic palladium templates. Pd nanocubes were subjected to galvanic replacement with Au3+ to produce PdAu nanocages having tunable dimensions (i.e., edge length, gold layer thickness, and hollow pore size), which allowed selectable positioning of the optical extinction maxima from the visible to the near infrared. These new nanocages circumvent the problems associated with previous Ag-derived gold alloy nanocages, which suffer from the toxicity of residual silver and the possible fragmentation of such alloyed nanostructures, thereby limiting their potential applications. In contrast, the present materials represent stable, nontoxic, tunable, and hollow plasmonic nanostructures. 其他題名： ACS Omega 出版者： United States: American Chemical Society 出版日期： 2016-09-30 出處： ACS omega, 2016-09, Vol.1 (3), p.456-463 資源來源： American Chemical Society (ACS) Open Access 版權： Copyright © 2016 American Chemical Society 版權： Copyright © 2016 American Chemical Society 2016 American Chemical Society 識別號： ISSN: 2470-1343 識別號： EISSN: 2470-1343 識別號： DOI: 10.1021/acsomega.6b00134 識別號： PMID: 31457139
