Optical and EPR spectroscopy of Er3+ in lithium yttrium borate, Li6Y(BO3)3:Er single crystals

Abstract: The energy levels of Er 3+ ions have been determined in lithium yttrium borate (Li 6 Y(BO 3 ) 3 )single crystals in a wide spectral range between 6000 -40000 cm -1 together with an analysis of the ground state, using optical and EPR spectroscopy. The crystal field splittings of the 4 I 15/2 ground state and those of nearly all excited states up to the 4 D 7/2 manifold have been obtained at low temperature from luminescence (T = 5 K) and absorption (T = 9 K) measurements, respectively. The numbers of experiment… Show more

“…Since no additional absorption lines appear in the low-temperature spectra, only one type of site can be assumed for Dy 3+ ions in the LYB lattice, as expected due to the isostructural property of Li 6 RE(BO 3 ) 3 crystals [16]. The same conclusion was drawn also from the optical and electron paramagnetic resonance (EPR) spectroscopy of Er 3+ doped LYB crystals [31]. It is remarkable that upon gradually increasing the temperature from 8 to 100 K, additional lines appear in the absorption spectrum, which can be related to the transitions from thermally populated higher states of the 6 H 15/2 ground state of Dy 3+ to various terms of the excited state.…”

“…Absorption spectra of LYB:Er 3+ , cEr = 1 mol% (black, with numbered peaks) and LYB: Yb 3+ , cYb = 0.1 mol% (red, dotted) between 10,250 and 10,450 cm −1 , measured at 9 K. Table 1. Positions and halfwidths of the absorption lines in the spectrum of LYB:Er 3+ and LYB:Yb 3+ crystals at T = 9 K shown in Figure 1, and Stark energies of the crystal field splittings are determined by L. Kovács et al [25] and J. Sablayrolles et al [22]. The measurement setup used for the spectral hole-burning experiments can be seen in Figure 2.…”
