Blue LEDs made from perovskite material shine bright thanks to hydrogen bonds

Nature, Published online: 15 July 2026; doi:10.1038/d41586-026-02161-9
Blue light-emitting diodes (LEDs) are needed for high-definition displays with wide colour range. Efficient, stable and colour-saturated blue LEDs containing emitters made of perovskites have now been fabricated by adding isomeric molecules that generate a network of hydrogen bonds, stabilizing the octahedral structure of the perovskite crystal. ...
