Evolution of the sizes and plasmonic properties of (Au core)−(Ag shell) nanorods is studied. Four plasmon bands are observed on the core−shell nanorods and their properties are investigated. The lowest‐energy one belongs to the longitudinal dipolar plasmon mode, the second‐lowest‐energy one belongs to the transverse dipolar plasmon mode, and the two highest‐energy ones are ascribed to octupolar plasmon modes.
