The origin of the spectra of rare earth ions arising from f->f and f->d transitions are surveyed. The parity forbidden luminescence of lanthanide ions can be strongly intensified by excitation via molecules characterized by high transition probabilities. Such behavior opens a route for creation of a class of new sophisticated materials. Luminescent materials based on heteroaromatic lanthanide cryptates are attractive as labels for advanced time-resolved fluoroimmunoassays, and molecular markers, their potential use is also conceivable in the field of luminescent displays, molecular photonics and highly luminescent materials in hybrid organic/inorganic glasses. The recent findings of lanthanide complexes trapped in sol-gel inorganic glasses based on silica and zirconia networks are discussed and the theoretical basis of their spectroscopy presented.
