Luminescent disordered nanostructures:synthesis and characterization of CdSe nano-agglomerates

摘要

A disorderly nanostructured CdSe nano-agglomerates (NAs)with tunable emission are synthesized in aqueous solution.Although the CdSe NAs have diameters of about 20nm that are larger than the Bohr radius of the crystal bulk,they show size-dependent emission similar to the CdSe nanocrystals.The CdSe NAs represent a collective energy state based on Anderson localization.
