Switchable interfacial reaction enables bright and stable deep-red perovskite light-emitting diodes

A switchable deprotonation reaction at the interface between the perovskite and electron-transporting layer enables bright deep-red perovskite LEDs emitting at 691 nm with a half-lifetime of about 50.3 h at 100 mA cm^–2.

Accelerated response speed of quantum-dot light-emitting diodes by hole-trap-induced excitation memory

The storage of holes in quantum-dot light-emitting diodes between high-frequency pulsed electrical excitations can create an excitation-history-dependent transient response, allowing the response speed of the devices to be increased.
