Abstract:
A facile spin cast route was developed to convert perpendicularly aligned nanorod assemblies of cadmium chalcogenides into their silver and copper analogues. The assemblies are rapidly cation exchanged without affecting 10 either the individual rod dimensions or collective superlattice order extending over several multilayers.
