摘要： Surface thiolation affects the size of gold nanoparticles and the presence of visible luminescence under UV stimulation. We explored these phenomena by analysing alkanethiolate coatings with different carbon chain lengths, from 3-mercaptopropionic acid to 16-mercaptohexadecanoic acid, synthesized by intense X-ray irradiation. Photoluminescence is present for the smallest nanoparticles, but its intensity becomes more intense as the carbon chain length increases, achieving a quantum efficiency of 28% with a 16-mercaptohexadecanoic acid coating. Synthesis of photoluminescent Au nanoparticles was optimized by alkanethiolate coatings. 出版日期： 2015-04-23 資源來源： Royal Society of Chemistry 識別號： ISSN: 1359-7345 識別號： EISSN: 1364-548X 識別號： DOI: 10.1039/c5cc01229e
