Article Synopsis
- - The study developed blue perovskite quantum dots (PQDs) using didodecyldimethylammonium bromide (DDAB) to improve quality by reducing surface defects and particle size variations.
- - After treatment with DDAB, the blue CsPbClBr PQDs produced a superior thin film in n-octane, showing better uniformity compared to untreated PQDs.
- - The resulting devices achieved a stable operational lifetime with an electroluminescence peak at 470 nm and an external quantum efficiency (EQE) of 1.63% at 2.6 V and 0.34 mA/cm², demonstrating a promising method for creating high-performance blue-emitting devices.
