Antibiotic ampicillin was introduced in InP-based quantum dot light-emitting diodes (QLEDs) to achieve charge balance via band alignment, enhancing external quantum efficiency from 0.9% to 4.7%. This is the first report of a QLED in which the same antibiotic material was applied to both the ETLs and HILs.
