Rare-earth ions incorporation into Lu2Si2O7 scintillator crystals: Electron paramagnetic resonance and luminescence study

Untangling the controversy on Ce3+ luminescence in LaAlO3 crystals

“…The corresponding resonances were ascribed to Nd 3+ considering the temperature dependence of the signals – they are not observed at about 20–30 K but appear only at 5–9 K. This is not typical for Ce 3+ ions but fully in line with Nd 3+ . 40,41,56 Moreover, the corresponding g factors are typical for Nd 3+ . The Ce2,3 signals are dominating in LaAP:Ce20%.…”

Determining the Hyperfine Structure and Clock Transitions for Kramers Rare-Earth Ions in a Crystal under a Magnetic Field: Beyond Spin Hamiltonian

“…Optical and EPR spectroscopy of the Yb 3+ :Lu 2 Si 2 O 7 crystal have been reported in the experimental work. How these spectra relate to their corresponding quantum transitions is clearly shown in Figure b.…”

“…In eq , the DFT-optimized coordinates ( R i , θ i , and ϕ i ) for the i th O 2– ligand in Table are taken as the input parameters. Therefore, three intrinsic CF parameters A̅ k ( R 0 ) ( k = 2, 4, 6) with reference distance R 0 (=2.4 Å), three power-law exponents t 2 , t 4 , and t 6 , and ζ are treated as adjustable parameters to fit both experimental optical spectra and angular-dependent EPR lines . The best fitted SPM parameters and ζ are given below where all of the oxygen ligands with distance R i smaller than 6 Å are considered in the fitting calculations.…”

“…In ref , angular dependencies of EPR lines in three orthogonal a * b , bc , and a * c planes for the Yb 3+ ion (with I = 0 and 1/2) in Lu 2 Si 2 O 7 have been reported. As mentioned before, the parameters in eq are obtained by fitting the optical and EPR spectra simultaneously.…”

“…Angular dependence of EPR lines of the Yb 3+ ion in the Lu 2 Si 2 O 7 crystal. For Yb isotope with I = 0, the central solid green lines and the blue dots represent the calculated and the experimental resonant magnetic fields (from ref ), respectively; for 171 Yb 3+ with I = 1/2, the calculated and experimental results (from ref ) are shown by black solid lines and red dots, respectively.…”
