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.
