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.
