Abstract
This communication describes a new method for producing stable, high c oncentrations of Sc2+ in optically clear CaF2 crystals. We have achiev ed Sc2+ concentrations as high as 3 x 10(18) cm(-3) without degradatio n of optical quality. We have converted as much as 5% of the scandium dopant to the divalent state. The concentration of divalent scandium i s stable during room temperature storage for periods of at least one y ear.
