Abstract

A facile strategy is illustrated to reversibly modulate CsPbBr₃ perovskite nanocrystal/Au nanoparticle heterostructures with the reversible formation and fragmentation of gold nanoparticles anchored to the corners and surface of CsPbBr₃ perovskite nanocrystals. The modulation process was performed under ambient conditions and could be conducted for cycles.
