Pb → Eu energy transfer mechanisms in the thermally annealed KCl: Pb 2+ , Eu 2+ system are examined by means of optical absorption, emission, and time decay spectra of the luminescence. The thermal annealing produced the formation of the Pb 2+ Suzuki phase and the results show that the Eu 2+ ions enter this phase by substituting for some Pb 2+ ions. The Pb → Eu transfer is found to be a very efficient process, with a very short transfer time. The analysis of the time decay signals shows that the transfer is a single pair mechanism; no migration of the excitation energy is experimentally detected.
