Ligand hyperfine coupling and electron structure features in the EPR spectra of Cu-doped multicomponent borate crystals: an interpretation based on the concept of the Jahn-Teller effect

Popis výsledku v původním jazyce

We report structural and spectroscopic properties of the yttrium and europium aluminum borates YAl3 (BO3 )4 and EuAl 3 (BO3 )4 doped by divalent copper with the content of 0.1 at.%. The tested samples have been synthesized by the sponta- neous solution-melt crystallization method. The X-ray diffraction analysis shows that the samples crystallize in the huntite structure with space group R32. The lattice parameters and atomic coordinates of YAl3 (BO3 )4 : 0.1 at.% Cu and EuAl3 (BO3 )4 : 0.1 at.% Cu single crystals are determined. It was found that the Cu ions substitute Al and locate in octahedral oxygen coordination complexes with the C2 site symmetry. During the EPR experiment, the second-order Jahn–Teller effect (or the pseudo-Jahn–Teller effect) and hyperfine structures are detected in both samples. The YAl3 (BO3 )4 : 0.1 at.% Cu sample manifests the ligand hyperfine (or superhyperfine) splitting related to the features of the host matrix.
