(a) Brief schematic illustration of the synthesis procedure where the precursor consisting of PbBr2 and CH(NH2)2Br dissolved in DMF solvent is added dropwise to toluene consisting of ligands and stabilizer under vigorous stirring at room temperature. (b) The absorption and PL spectra of FAPbBr3 nanocrystals in toluene solution, for reference the thin film PL is also overlaid on the solution PL. The inset shows FAPbBr3 NC in toluene under ambient light and under UV exposure.
