Crystal structure-selective formation and carrier dynamics of type-II CdS–Cu31S16 heterodimers†
Abstract
Anisotropically phase-segregated CdS–Cu31S16 heterodimers with type-II band alignment were spontaneously formed by selective growth of monoclinic Cu31S16 phases on preformed hexagonal CdS phases. The photo-induced carrier dynamics of the heterodimer was investigated by fluorescence and transient absorption measurements.
