The upconversion of photons allows for a more efficient use of light: 2 photons are converted into a single photon having higher energy. Researchers at KIT 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.

Metal-organic frameworks (MOFs) are highly ordered molecular systems that consist of metallic clusters and organic ligands...
