Highly luminescent CsPbBr3 nanorods synthesized by a ligand-regulated reaction at the water-oil interfaceElectronic supplementary information (ESI) available: Experimental section and supplementary figures. See DOI: 10.1039/c8tc06317f

For the first time we report highly luminescent CsPbBr 3 nanorods (NRs) with aspect ratios around 2-10 through chemical transformation from Cs 4 PbBr 6 nanocrystals. Detailed structural characterization shows that the NRs are cubic phase with uniform growth direction. The NRs are formed through an oriented-attachment mechanism assisted by the ligand-regulation at the water-oil interface. We have synthesized highly luminescent CsPbBr 3 nanorods through an oriented-attachment mechanism assisted by the ligand-regulation at the water-oil interface.
