Figure S1. Color change in CsPb(BrxI1-x)3 for x increasing from x=0 to x=1 left to right.
Materials Solutions were prepared in extra dry dimethyl sulfoxide (DMSO) (Acros, 99.7%) using CsBr (Aldrich, 99.999%), CsI (Aldrich, 99.9%), PbBr2 (Aldrich ≥98%), PbI2 (TCI, 99%) precursors and mixed in the appropriate molar ratios for the CsPb(BrxI1-x)3 target composition. Solutions were prepared under an inert atmosphere in an N2 glovebox with
