Abstract
Five multi-hydrogenic optical centers were studied in SrF2:Pr3+ and Ca F2:Pr3+ crystals. These centers are created by hydrogenic ions replaci ng those F- ions located between the Pr3+ and its charge compensator i n the C-4v center. The D-1(2) fluorescence lifetimes of the multi-D- c enters decrease with increase in the number of D- ions present. The 10 K bleaching rates decrease from H- to T- under identical excitation. Thermal recovery of bleached centers occurs near 100 K for all three i sotopes.
