Electron paramagnetic resonance and photoluminescence study on local structure of Gd3+ ions in Gd-doped CaF2 crystals
Shirui Luo, Fang Tan, Dapeng Jiang, Honggang Liu, Tingyu Liu, Liening Wei, Yu Liu, Zhen Zhang, Fengkai Ma, Zhonghan Zhang, Huamin Kou, Huaize Qin, Jingguo Zhu, Junjie Hu, Wei Hong, Liangbi SuThe EPR spectra of CaF2 with different Gd-doping concentrations were fitted, combined calculations revealed that most of the Gd3+ in 1.22 at% Gd:CaF2 are distributed as a dimer with a distance of 7.7 Å distributed along the [110] direction.
