Fig. 2From: Modulation Technique of Localized Surface Plasmon Resonance of Palladium Nanospheres by Coating with Titanium Dioxide Shell for Application to Photothermal Therapy AgentMorphological characterization of Au/PdNSs and Au/PdNSs/TiO2. (a) TEM image and (b) size distribution for (A) Au/PdNSs and (B) Au/PdNSs/TiO2. (C) (a) XRD patterns of Au/PdNSs/TiO2 and (b) JCPDS data of palladium. (D) XPS spectra of Au/PdNSs/TiO2 mounted on a glass plate. Narrow spectra for (a) Ti2p, (b) Au4f, and (c) Pd3d. The binding energies were corrected using the C1s level at 284.8 eV as an internal standardBack to article page
