英文摘要	We report a facile one-pot strategy of "ill-defined gold nanoparticles (ID-GNPs)" to prepare dual functional gold nanoparticles. The ID-GNPs were prepared in a simple way by tuning the morphology of the regular GNPs with a tiny amount of cetyltrimethyl ammonium bromide (CTAB). The prepared ID-GNPs comprise both quasi-spherical and elongated gold nanoparticles, which allow the presence of coarse surfaces and high density of hot spots. The substrates fabricated with ID-GNPs show dramatic Raman enhancement for p-aminothiophenol (PATP). PATP can be detected even at a concentration of 10(-12) mol L-1. Meanwhile, these ID-GNPs can efficiently convert absorbed photons into heat when irradiated with 808 nm laser. The temperature of the ID-GNPs dispersion can be enhanced 26.0 degrees C within 10 minutes, which is capable of inducing the phase transition of a temperature-sensitive supramolecular system. Our study suggests that with the strategy of 'ill-defined gold nanoparticles', these two different functionalities can be achieved on one platform.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000351556800088&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Chemistry, Multidisciplinary; SCI(E); EI; 0; ARTICLE; 34; 27120-27125; 5
