Cs4pbbr6 synthesis
WebWe report here a new one-step approach for the synthesis of Cs4PbBr6 nanocrystals (NCs), as well as the exploration of its formation process. Mixing three independent precursors of Cs, Pb, and Br in a cuvette, we monitor the evolution of Cs4PbBr6 NCs by in situ absorption spectroscopy, the formation of which features a sharp absorption peak at ... WebHigh-quality and millimeter-sized perovskite single crystals of CsPbBr3 and Cs4PbBr6 were prepared in organic solvents and studied for correlation between photocurrent generation and photoluminescence (PL) emission. The CsPbBr3 crystals, which have a 3D perovskite structure, showed a highly sensitive photoresponse and poor PL signal. In contrast, …
