Abstract:
Densitycontrollablegoldnanorods(GNRs)weresynthesizedwithintheP(NIPAM-NVP)hydrogelnetworkbyadjustingthegrowthmodeofGNRs.Thethermo-responsivepropertyandtheinfluenceofGNRsdensityonthermo-responsiveandopticalpropertieswereinvestigated.ItisfoundthatthepositionandintensityoftheLSPRforthecompositechangeobviouslywithtemperatureandthischangeisfoundtobefullyreversible.Furthermore,thenanocompositesshowexcellentSERSenhancementeffectandtheSERSintensityoftheNileBlueA(NBA)dramaticallyincreaseswhenthetemperatureisincreased.
