"without compromising material quality... tune optical properties by tuning bandgap, which determines light color emitted... green-emitting perovskite quantum dots in either chlorine or iodine solution, then run through microfluidic system incorporating light source enabling precise reaction control by ensuring rapid, uniform light exposure across 10µ/ reaction droplet... makes QDs move closer to blue when chlorine present, red when iodine present... bandgap control: controlling energy/ light amount... optoelectronic devices"
