Different types of Binary Nanoparticle Superlattices (BNSLs) have been self-assembled from monodisperse 8.7 nm CdSe and 5.5 nm Au nanocrystals. Fluorescence spectroscopy studies of AlB2-type BNSL of CdSe and Au nanocrystals revealed considerably decreased fluorescence and a shortened fluorescence lifetime of the CdSe NCs in BNSLs compared to the CdSe-only sample.
