Synthesis of Yb3+-Doped Cs2NaScF6 Single Crystals and EPR Spectroscopy of the Dopant Yb3+ ion
摘要
Single crystals of Yb3+-doped Cs2NaScF6 are synthesized under hydrothermal conditions and dopant Yb3+ ions are studied using electron paramagnetic resonance spectroscopy. The paramagnetic Yb3+ center of cubic symmetry is detected. The parameters of the corresponding spin Hamiltonians and the ground state Г6 are determined. A structural model of the complex under study is proposed. The experimental results are analyzed by comparison with those for the paramagnetic Yb3+ ion in other lattices.
