Two become one: How to turn green light blue

The upconversion of photons allows for a more efficient use of light: Two photons are converted into a single photon having higher energy. Researchers now showed for the first time that the inner interfaces between surface-mounted metal-organic frameworks (SURMOFs) are suited perfectly for this purpose – they turned green light blue. The result opens up new opportunities for optoelectronic applications such as solar cells or LEDs.
