  Abstract: Presently, phosphors and luminescent   materials for lighting, telecommunications, displays, security   inks and marking, as well as for probes in biosciences represent   one third of the total value of the lanthanides used worldwide.   If optical glasses and laser materials are added, this figure is   close to 40%, explaining the large interest that the scientific   community is devoting to such materials. The present review   focuses on the design of highly luminescent lanthanide complexes   and discusses all aspects needing optimization. Reference is made   to the mastering of the various energy migration processes in   luminescence sensitization by organic ligands, to minimizing   non-radiative deactivation mechanisms, as well as to other   parameters such as the radiative lifetime, the refractive index,   and the benefit of inserting luminescent complexes into   inorganic-hybrid structures. Comparative tables list the most   luminescent complexes emitting in the visible and near-infrared   ranges and the best chromophores are pointed out.
