Colloidal synthesis of homogeneously alloyed CdSexS1−x nanorods with compositionally tunable photoluminescence

Abstract

Homogenously alloyed CdSe_xS_1−x nanorods with controlled aspect ratios are synthesised by a hot-injection colloidal route. The optical absorption and photoluminescence emission are compositionally tunable with chalcogen ratios. The synthetic protocol is sufficiently robust to allow good control of rod aspect ratios, with low polydispersities, suited for their rational assembly into superstructures.
