✦ Synopsis

Energy transfer (ET) between Cc3++ Tm3+ and Ce3++ Tb3+ in p h osphate glass was measured in the temperature range 7-300 K. The efficiency of ET between Ce3' and Tm3+ is independent of temperature, while temperature increasr; is observed in the Ce3+-Tb3+ pair. This is explained by the increase with temperature of the overlap between Ce3* emission and Tb3* absorption bands.

Energy transfer between Ce3+ and Tb3+ in rare earth pentaphosphates was studied versus Ce3+ concentration and temperature. Within this chain-type structure the energy diffusion is very sensitive to atomic substitution and -this process is operating via the Ln-0-P-0-Ln links. The energy transfer effi
