## Abstract Optical absorption and electrical conductivity of Inβdoped CdF~2~ crystals have been measured at various temperatures. The results confirm the assumption of Trautweiler et al. [12] that the In^3+^ centers offer two localization possibilities t o the electrons introduced by annealing the
Kozanezcki, Phys.Rev B 59 1999 R2525 . PL of Eu in SLs, in contrast to bulk CaF :Eu crystals, fades out considerably 2 under continuous UV excitation. This is mainly due to tunneling-assisted photoionization of Eu 2q . We have measured the PL time dependence in uniformly and selectively doped SLs wi
