Abstract

A short review of our published and unpublished studies and investigations of other authors on the sensitization by dyes of near-IR fluorescence of Yb(III) and Nd(III) in solutions and polymers is given. Yb(III) fluorescence lifetimes in different solvents and rate constants of intramolecular energy transfer from triplet state of Eosin to Yb(III) were measured for such systems. Mechanisms of non-radiative transition in Yb(III) salt solutions is discussed. The sensitization of Yb(III) fluorescence by eosinate methylene blue in PMMA was found to occur. Sensitized near-IR fluorescence of Nd(III) also has been detected under two-photon picosecond excitation in DMSO and under one-photon steady-state excitation in POCl₃ + SnCl₄ through intra- and intermolecular energy transfer respectively.
