“…The sharp increase observed at 10.5 and 11 eV indicates the beginning of host absorption of LiSAF and LiCAF, respectively. This is in good agreement with earlier results for LiSAF:Tm [7] and pure LiCAF [8] by luminescence methods.…”

“…Therefore, the spectroscopic data of Eu doped LiCAF and LiSAF is particularly useful for reliable identification of overlapping 4f-5d and CT transitions of other rare earths (for example Tm 3+ ) in the same host crystals. It has been successfully used to determine the position of the CT state in Tm doped LiSAF helping to identify its role in the relaxation mechanism of electronic excitations [7].…”

Optical properties of Eu doped LiCaAlF 6 and LiSrAlF 6 crystals grown by Czochralski technique were investigated in vacuum ultraviolet using synchrotron radiation. The 5d→4f and 4f→4f emissions from Eu 2+and Eu 3+ ions, respectively, were detected under excitation due to the inter-configurational 4f 7 →4f 6 5d and 4f 6 →4f 5 5d transitions. The 4f emission of Eu 3+ is efficiently excited via F¯ to Eu 3+ charge transfer absorption and excitonic states localised near impurity. The yield of 5d→4f emission of Eu 2+ in both crystals is high in the intra-center excitation and considerably less through excitation via host absorption limiting their performance for scintillation purposes.

“…There are two exceptions. First, the VUV excitation spectra of Tm 3+ in the LiMAlF 6 (M = Ca, Sr) hosts [77,78], and the VUV absorption spectrum of Nd 3+ in LiCaAlF 6 [75], have been reported. In this host, the Ln 3+ ions are situated at the Ca 2+ D 3d site in a trigonally elongated octahedral coordination.…”

Vacuum ultraviolet excitation spectra at ∼10 K have been recorded for 4f N → 4f N −1 5d transitions of Cs 2 NaYF 6 :Ln 3+ (Ln = Nd, Sm, Eu, Tb, Ho, Er, Tm). In these high bandgap hosts the lanthanide ions occupy octahedral symmetry sites. The spectra comprise broad, structured bands and in most cases the individual vibronic structure is not resolved. Simulations of the relative intensities and band positions in the spectra have been made by using parameter values from previous studies and/or by employing values from similar systems or estimating trends across the lanthanide series, without data fitting or parameter adjustments. The agreement with experimental results is reasonable except where the luminescent state being monitored is not efficiently populated nonradiatively from the 4f N −1 5d state, or where additional bands are present. The latter are readily assigned to charge transfer transitions or the near-excitonic band. Comparison of the spectra has been made with those of other high symmetry lanthanide ion systems.

“…Finally, an exciton-like Ln 4þ þ e À formation that relaxes predominantly into the 4f n manifold through dipole-dipole or multipole interactions, is created for example [7]. However, the excitation mechanisms for f-f emissions are more complicated including also such possibilities as charge transfer absorption and energy transfer via intrinsic and/or extrinsic host excitations [8].…”

Emission and excitation spectra as well as decay curves of Er 3þ and Tm 3þ ions doped into SrF 2 crystals have been studied using timeresolved vacuum-ultraviolet spectroscopy under pulsed synchrotron radiation at 8 K. In emission spectrum for crystals doped with Er 3þ ions together with well-known emission caused by spin-forbidden 4f 10 5d ! 4f 11 transitions (decay constant in the microsecond range), a new fast emission band detected at 146.5 nm (decay constant is less than 0.6 ns) has been revealed. It was shown that excitation spectra of f-f and d-f emission bands for Er 3þ and Tm 3þ ions in SrF 2 have opposite behaviors in the spectral range corresponding to energy of their 4f nÀ1 5d configurations. These peculiarities and energy transfer mechanisms were analyzed. r
