Inorganic LEDs articles from across Nature Portfolio

Inorganic LEDs are light-emitting diodes (LEDs) made from a crystalline semiconductor. The optical emission wavelength can be selected by varying material composition. Example active regions include germanium, gallium arsenide, gallium nitride and indium phosphide. Inorganic LEDS are prized for their low power consumption and are rapidly replacing conventional incandescent light bulbs.

Rational adjustment to interfacial interaction with carbonized polymer dots enabling efficient large-area perovskite light-emitting diodes

Using carbonized polymer dots, the interfacial properties between perovskites and the hole transporter can be optimized. The anion-dominated interface breeds a dense and homogeneous emitting layer, enabling 20.2% external quantum efficiency for 225 mm² large-area light-emitting device.

How we made the microLED

Micro-light-emitting-diode display applications are growing quickly as technology companies begin to use them in a range of products. Key to the development of these applications was the miniaturization of gallium nitride light-emitting diodes. Hongxing Jiang and Jingyu Lin recount how this was achieved.

MicroLEDs get in line

By selectively engineering the surface roughness of micro-light-emitting-diode chips, and thus the strength of the van der Waals forces that bond them to a substrate, large-area displays can be created via a fluidic-assisted transfer method.

Lanthanide doped lead-free double perovskites as the promising next generation ultra-broadband light sources

Efficient ultra-broadband emitter is realized by using multi-Ln-doped Cs₂Ag(In/Bi)Cl₆ lead-free double perovskite (DP) coupled with “DPs-in-glass composite” (DiG) structure. The synergy of self-trapped exciton together with the energy transition induces this ultra-broadband emission emerge.
