Colloidal synthesis of homogeneously alloyed CdSe(x)S(1-x) nanorods with compositionally tunable photoluminescence.

Homogenously alloyed CdSe(x)S(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.
