“…The infrared emission spectrum recorded The use of this selective excitation technique gives energies with a precision of ±1 cm −1 . The results obtained agree with those given by the literature [24][25][26][27] by using the usual method of combined analysis of the emission and absorption spectra.…”

We are interested, in this work, in determining the Stark sub-level of Er 3+ ions doping a KY 3 F 10 single crystal with a molar concentration of 1%. We have used a new method of measurement of energies of the ground level and emitting levels from excitation and anti-Stokes emission spectra recorded at liquid nitrogen temperature. This technique is based on a spectral analysis of the anti-Stokes emissions recorded after selective excitation with a red dye tunable laser. Thus, we could determine the Stark sub-levels of the ground and the principal emitting levels in the infrared, visible and near-UV ranges with a very good precision.

“…(iii) Variations in the azimuth angles φ j were not considered in the calculations. Strictly speaking, the azimuth angles φ j would also suffer a slight change Δφ due to the above size mismatching substitution, which could induce tiny modification in the calculated b 4 4 and b 4 6 . However, because of the small magnitudes of the rank-4 and rank-6 ZFSs, the errors due to ignoring the variation of φ j may be taken as negligible.…”

“…In addition, KY 3 F 10 exhibit useful laser and luminescence properties when doped with Er 3+ , Eu 3+ , Ho 3+ and Pr 3+ [4][5][6][7][8][9][10][11]. Usually, these properties are sensitively related to the local environment (e.g., bonding length and angles) for these rare-earth impurities on the Y 3+ site.…”

The electron paramagnetic resonance parameters, zero-field splittings (ZFSs) b 0 2 , b 0 4 , b 4 4 , b 0 6 , b 4 6 and the g factors for Gd 3+ on the tetragonal Y 3+ site in KY3F10 are theoretically studied from the superposition model for the ZFSs and the approximation formula for the g factor containing the admixture of the ground 8 S 7/2 and the excited 6 L 7/2 (L=P, D, F, G) states via the spin-orbit coupling interactions, respectively. By analysing the above ZFSs, the local structure information for the impurity Gd 3+ is obtained, i.e., the impurity-ligand bonding angles related to the four-fold (C4) axis for the impurity Gd 3+ center are found to be about 0.6 • larger than those for the host Y 3+ site in KY3F10. The calculated ZFSs based on the above angular distortion as well as the g factors are in reasonable agreement with the observed values. The present studies on the ZFSs and the local structure would be helpful to understand the optical and magnetic properties of this material with Gd dopants.
