Cu2−xS纳米棒的局部表面等离子体共振（LSPR）在阴离子交换的初始Cu2−xS/Cu2−xTe核/壳阶段被淬灭，然后随着Cu2−xTe进入纳米棒而恢复。核心内的相变解释了这种行为，说明了阴离子交换产生的复杂性。
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.
