The luminescence of trivalent lanthanide ions has been studied intensively and has found applications in lasers, lighting, optical telecommunications, drug delivery, cancer therapy and various other fields. In the last decades, lanthanide-doped phosphors and crystals as well as complexes with organic and inorganic ligands have received more attention with respect to their preparation and applications. This review presents the basics of lanthanide photophysics as well as the numerous applications of lanthanide doped luminescent materials.
