Abstract
Control over the organization of quantum rods was demonstrated by changingthe surface area at the air–liquid interface by means of the Langmuir–Blodgett(LB) technique. The LB isotherm of CdTe quantum rods capped with a mixtureof alkylphosphines shows a transition point in the liquid–solid state, which iscaused by the inter-rod reorganization. As we observed, at low surface pressurethe quantum rods are assembled into round-shaped aggregates composed of amonolayer of nanorods packed in limited-size clusters with random orientation. Theincrease of the surface pressure leads to the rearrangement of these aggregatesinto elongated bundles composed of uniformly oriented nanorod clusters. Furthercompression results in denser packing of nanorods aggregates and in the transformationof monolayered domains into a continuous network of locally ordered quantumrods.
