Xiaoqing Huang, Shaoheng Tang, Biju Liu, Bin Ren and Nanfeng Zheng Enhancing the Photothermal Stability of Plasmonic Metal Nanoplates by a Core-Shell Architecture Advanced Materials 23
Plasmonic core-shell bimetal nanoplates: A facile seeded-growth strategy is developed to prepare uniform plasmonic Pd@Ag core-shell bimetallic nanoplates. The as-prepared Pd@Ag nanoplates are not only uniform in both size and shape, but also display tunable SPR properties and significantly enhanced photothermal stability as compared with 2D pure-Ag nanostructures. They can thus be readily used as stable substrates for NIR surface-enhanced Raman scattering and as NIR absorbers for photothermal cancer therapy.
