description

Lead halides are used extensively to prepare perovskite-based devices but it is less known that lead halides can also form luminescent complexes in solvents. Using polyethylene glycol as a solvent, a lead bromide complex with a photoluminescence quantum yield over 20% is obtained and the photoluminescence peak can be shifted around 50 nm with different alkylammonium bromides.
