Heterostructures of Cu2−xS/Cu2−xTe plasmonic semiconductors: disappearing and reappearing LSPR with anion exchange†‡
Abstract
Localized surface plasmon resonance (LSPR) of Cu2−xS nanorods is quenched during the initial Cu2−xS/Cu2−xTe core/shell stage of anion exchange then returns as Cu2−xTe progresses into the nanorod. Phase change within the core accounts for this behaviour illustrating the complexity emergent from anion exchange.
