Light-emitting devices based on semiconductors have a huge impact on modern technologies. The brightness and durability of light-emitting diodes make them ideal for displays, while semiconductor lasers have been used in everything from optical communications systems to compact disc players. But these applications have been limited by the lack of materials that can emit blue light efficiently.

Perovskite quantum-dot-based light-emitting diodes (QLEDs) possess the features of high-quality lighting and displays1. Thus red and green QD-LEDs with a maximu...
