The luminescence associated with the Eu/sup 3 +/ ion in LiEuCl/sub 4/ has been studied at cryogenic temperatures under conditions of high resolution. Emission was observed to originate from both the /sup 5/D/sub 0/ an /sup 5/D/sub 1/ excited states, and transitions to the /sup 7/F/sub 0/, /sup 7/F/sub 1/, /sup 7/F/sub 2/, /sup 7/F/sub 3/, and /sup 7/F/sub 4/ ground levels were observed. The fine structure observed within these emission bands was found to be consistent with the existence of an effective D/sub 4/ site symmetry for the emitting Eu/sup 3 +/ species, even though the europium polyhedron was found to be that of a bisdisphenoid.
