โœฆ Synopsis

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 efficiency is strongly influenced by the effect of temperature on the overlap between the CeW and Tb* bands.
