EPR and optical spectra of Yb3+ in CsCdBr3: Charge-transfer effects on the energy-level structure of Yb3+ in the symmetrical pair centers

Malkin B.; Leushin A.; Iskhakova A.; Heber J.; Altwein M.; Moller K.; Fazlizhanov I.; Ulanov V. (2000)

Electron paramagnetic resonance (EPR), optical absorption, fluorescence, and excitation spectra of CsCdBr3:1% Yb3+ single crystals were taken at 4.2 K. An analysis of the dependence of the EPR spectrum on the magnetic-field ...
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 ...
Far-infrared spectroscopy investigation and lattice dynamics simulations in CsCdBr3 and CsCdBr3: R3+ crystals

Malkin B.; Iskhakova A.; Kamba S.; Heber J.; Altwein M.; Schaack G. (2001)

Polarized infrared reflectivity spectra of CsCdBr3 crystal were measured at temperatures 20 and 300 K in the wave number range of 10-650 cm-1. Frequencies and damping of the optically active lattice modes at the Brillouin ...
Hyperfine structure of submillimeter EPR spectra of non-kramers lanthanide ions in crystals

Shakurov G.; Tarasov V.; Malkin B.; Iskhakova A.; Kasatkina L.; Heber J.; Altwein M. (1998)

The hyperfme structures of submillimeter EPR spectra of CsCdBr3:Tm3+ and CaF2:Dy2+ single crystals have been resolved and analyzed. The crystal field parameters and the magnetic hyperfine constants are obtained from fitting ...
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 ...
Spectra and relaxation of electronic excitations in CsCdBr3:Yb3+ and CsCdBr3:Nd3+ monocrystals

Gafurov M.; Iskhakova A.; Kurkin I.; Kurzin S.; Malkin B.; Nikitin S.; Orlinskii S.; Rakhmatullin R.; Shakurov G.; Tarasov V.; Demirbilek R.; Heber J. (2002)

Experimental and theoretical studies of the optical and EPR spectra, and the spin-lattice relaxation in CsCdBr3 crystals containing 0.1, 0.3 and 1.0 mol.% of impurity Yb3+ ions have been fulfilled. In the optical excitation ...
Submillimeter electron-nuclear excitation spectra in CsCdBr3:Ln3+ (Ln=Tm, Ho) crystals

Tarasov V.; Shakurov G.; Malkin B.; Iskhakova A.; Heber J.; Altwein M. (1997)

The ESR spectra of single and pair impurity centers of thulium and holmium ions in CsCdBr3:Tm3+ and CsCdBr3:Ho3+ crystals are measured in the frequency range 160-400 GHz. Analysis of the characteristic features of the ...
Submillimeter EPR spectroscopy of lanthanide compounds: Pair centers of Ho3+ in CsCdBr3

Malkin B.; Iskhakova A.; Tarasov V.; Shakurov G.; Heber J.; Altwein M. (1998)

High-frequency EPR spectra corresponding to magnetic dipole transitions between the doublet-singlet-doublet group of the lowest crystal field levels of the trigonal single ion and the symmetric dimer centers in CsCdBr3 ...
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 ...
