Precise colour tuning just by changing the anion: " Based on the NanoRobo microfluidic platform the researchers unveiled two years ago, the Nanocrystal (NC) Factory as the authors call it starts with cesium lead bromide perovskite quantum dots and introduces various halide salts to precisely tune their fluorescence color across the entire spectrum of visible light. Anions in these salts replace the bromine atoms in the green-emitting dots with either iodine atoms (to move toward the red end of the spectrum) or chlorine atoms (to move toward blue)." Wonderful stuff.
