Abstract

Luminescence decay curves from the $_5)D₁ state of Eu³⁺ in the cubic hexachloroelpasolite crystals Cs₂NaSm_xEu_0.1Gd_0.9-xCl₆ have been measured at 80 K and 300 K. At this concentration of Eu³⁺, cross-relaxation to nearby Eu³⁺ acceptor ions and energy-transfer to the ⁴G_5/2 state of Sm³⁺ occur at both temperatures. Excellent agreement between the experimental decay curves and the a priori calculated curves is achieved by using a recently developed discrete shell model for energy transfer.
