The particle temperature calculation indicated that evaporation begins with a liquid droplet AuNP surrounded by a supercritical layer at temperatures below the boiling point of gold. By applying high pressure, we are able to obtain a clear picture of the evaporation event, which was not possible at ambient pressure because the forming bubble caused particle temperatures to rise uncontrollably. In this study, we shed light on the critical role of the supercritical layer formed around the AuNP under high pressure during laser-induced evaporation."},"publication_date":"2016-01-12","publication_name":{"en":"Physical Chemistry Chemical Physics","ja":"Physical Chemistry Chemical Physics"},"volume":"Vol.18","number":"No.6","starting_page":"4994","ending_page":"5004","languages":["eng"],"referee":true,"identifiers":{"doi":["10.1039/C5CP07395B"],"issn":["1463-9084"]},"published_paper_type":"scientific_journal"}}
