  • Excitons and rare-earth ions in CsCdBr3 
    Heber J.; Demirbilek R.; Nikitin S. (2004)
    CsCdBr3 has a quasi-linear crystal structure. It consists of covalently bound [CdBr]6 4- chains separated by chains of Cs+ ions. The trivalent rare-earth (RE) ions substitute for divalent Cd ions forming predominantly pair ...
  • Local lattice structure, crystal field and energy level patterns in CsCdBr3:Tm3+ crystals 
    Heber J.; Lange M.; Altwein M.; Malkin B.; Rodionova M. (1998)
    In CsCdBr3, Tm3+ substitutes for Cd2+. It predominately forms symmetric dimer centers and single-ion centers, both of trigonal symmetry. The energy level schemes of both centers were determined by EPR and site-selective ...
  • The rare-earth centers in CsCdBr3 
    Heber J.; Demirbilek R.; Altwein M.; Malkin B.; Tarasov V. (2002)
    CsCdBr3 crystallizes in the quasi-linear CsNiCl3 structure. It possesses linear chains of [CdBr6]4- octahedra separated by parallel chains of Cs+. Trivalent rare-earth (RE) ions substitute for the divalent Cd ions. The ...
  • Theoretical studies of nonradiative 4f-4f multiphonon transitions in dielectric crystals containing rare earth ions 
    Malkin B.; Pukhov K.; Saikin S.; Baibekov E.; Zakirov A. (2007)
    Detailed calculations have been performed of multiphonon relaxation rates of optical excitations in Nd-doped LiYF4 and Pr-doped CsCdBr3 crystals in the frameworks of the exchange charge model of the crystal fields and rigid ...
