摘要：

Luminescence decay curves from the (4)G(5/2) state of Sm3+ in the cubic hexachloroelpasolite crystals Cs2NaSmxY1-xCl6 (x = 0.005 tp x = 1) have been measured in the temperature range 10-300 K. Energy transfer from the (4)G(5/2) to the F-6(j) states occurs at all concentrations studied. At intermediate concentrations the decay curves are strongly non-exponential and are interpreted using a recently developed shell model. Extensions of the model which may provide a better description of the data are briefly discussed.
