The preparation of single crystals of Beta -alumina containing two trivalent lanthanide species is described. The use of eutectic melts enables the two rare earth species to be introduced during a single ion exchange process. Energy transfer in crystals containing Ce3Nd 3 and Ce3Tb 3 is shown. High transfer efficiencies were measured for crystals with low sensitizer-to- activator ion concentration ratios. Up-conversion processes were observed in crystals doped with Yb3 and Er 3 ions.
