The Use of Multiple Ion Exchange to Produce Energy Transfer in Beta Aluminas

Abstract

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 Ce+3/Nd +3 and Ce+3/Tb +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 Yb+3 and Er +3 ions.
