Abstract
Adv. Mater. 2019, 31, 1905143 In the originally published article, the composition of the CsPbI3−xBrx precursor was reported incorrectly in the Experimental Section. The correct molar ratio of HPbI3+x:PbBr2:CsI is 1.36:0.74:2, rather than the quoted 1:1:2. The 1:1:2 molar ratio does not result in the reported characteristics. The revised text for the precursor part of the Experimental Section is as follows: CsPbI3-xBrx Precursor: Synthesized HPbI3+x:PbBr2:CsI with 1.36:0.74:2 (0.68:0.37:1) molar ratio at 1 m was dissolved (DMF:DMSO = 1:1.4) and stirred at 60 °C in a N2 glove box for 2 h. For the PbCl2-doped precursor, different concentrations of PbCl2 were synchronously added into the above-prepared solution.
