Terbium (III) ion can form stable coordination complexes or chelates with a variety of organic ligands, exhibiting high stability and strong luminescence. In these complexes, the energy absorbed by the organic chromophore at its characteristic excitation wavelength is transferred to a triplet state of the molecule and then intramolecularly transferred to a resonance level of the terbium ion, which finally emits luminescence. The main features of this process are a large Stokes shift, a narrow-band emission (specific of the terbium ion) and a long luminescence lifetime. This book reviews the characteristics of the TSL process and particular attention is paid to the development of TSL optosensors, due to their potential applications in a wide range of fields.
