Researchers from the University of Amsterdam (UvA), in collaboration with Japanese partners, have determined the relation between the bandgap energy of single cesium lead bromide nanocrystals (CsPbBr3 NCs) and their size and shape. By studying individual NCs being either isolated or surrounded by 'neighbors', they explicitly visualized for the first time band structure modification introduced by effective coupling between semiconductor NCs upon close contact.
