Optical and EPR characterization of Er3+ centers in SrTiO3 single crystals
Original language description
We report on optical absorption and EPR spectroscopy studies of low Er doped (50 ppm) SrTiO3 single crystals. In the region of 400?650 nm a set of optical intra-configurational f?f transitions from the 4I15/2 ground state to the excited 4F9/2, 4S3/2, 2H11/2, and 2H9/2 Stark sublevels of the Er3+ impurity ions were observed and identified. At T=2K the number of registered optical transitions evidences the presence of only one type of Er3+ centers with non-cubic symmetry. The system of the energy levels for Er3+ excited states is determined. The X-band EPR spectra at 5.2 K revealed the rhombic symmetry of Er impurity centers. The components of a rhombic g-tensor were defined. It was suggested that Er ions substitute Sr ions in A-sublattice sites.
