CH₃NH₃PbBr₃ perovskite nanocrystals (PeNCs) are expected as various optical devices such as organic light-emitting diodes.In this paper, we attempted to control size of PeNCs by changing ligand in ligand-assisted reprecipitation method.Improvement the performance of light-emitting device can be achieved by controlling PeNCs size.
