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.

Nanodiamonds can host atom-sized light emitters for quantum sensing and imaging, but making nanodiamonds that are small, crystalline and uniform has been difficult. A single-step process for making nanodiamonds only 3–4 nanometres in size uses planar carbon ‘nanographene’ molecules with hydrogen atoms on the edges, and can be adapted to generate fluorescent nanodiamonds.
