摘要： Plasmon-enhanced heating has been directly studied through the observation of the change of Raman spectra of Au-Fe2O3 composite catalyst and Fe2O3 alone under 532 nm laser excitation. Strong plasmonic heating is observed in the Au-Fe2O3 nanoparticle composite which can be plasmonically heated 200 °C higher than Fe2O3 under the same laser power irradiation. A large downshift and broadening of Raman peaks are successfully observed, which is consistent evidence for the extreme plasmonic heating process. In addition, different geometries of the Au-Fe2O3 composite pattern are also achieved in this study by precise control of the movement of the laser spot irradiation. 其他題名： MRX 其他題名： Mater. Res.
