Paper Abstract

Luminescence decay curves from the $_5)D1 state of Eu3+ in the cubic hexachloroelpasolite crystals Cs2NaSmxEu0.1Gd0.9-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 4G5/2 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.
