Abstract

Red light, green light! Emission through three-photon upconversion processes from polymeric organic-lanthanide complexes (lanthanide, Ln = Tb, Eu) was observed upon excitation of the tripodal organic ligand at 845 nm. Multiphoton absorption by the ligand followed by a transfer of energy to Ln (see picture; S = singlet state, T = triplet state) gives rise to characteristic Eu (red) or Tb (green) emission.
