“…In the spectra of the compounds under investigation, the reabsortion for the zero-phonon line around 980 nm has not been observed. However, the strong overlap of the absorption and emission spectra originating from the transitions between the four Stark components of the ground 2 F 7/2 and the three components of the excited 2 F 5/2 state of Yb 3+ is well known for various matrices [1,19]. The relationship between the total CF splitting of the 2 F 7/2 and 2 F 5/2 levels allows to suggest the energy level scheme for both kinds of the investigated samples.…”

“…The Yb 3+ ion can create laser action in the IR range around 1000 nm and has several advantages when compared to the Nd 3+ -doped systems already employed in various laser materials. The intense and broad Yb 3+ absorption lines are well suited for the IR laser diode pumping [1].…”

This contribution is devoted to the new ytterbium-doped alkali metal lutetium double phosphates and their structural and spectroscopic characterisations. The absorption, emission and excitation spectra have been measured at 4, 10 and 293 K in the VUV to IR range. The results have been compared with the analogous yttrium phosphates. The luminescence spectra of the double phosphates have been recorded using various excitation lines, including the synchrotron radiation. The low temperature absorption and emission spectra in the region of the 2 F 7/2 ! 2 F 5/2 transition together with the IR spectra have been used to assign the electronic and vibronic components. Detailed analysis of the Yb 3+ -doped sodium lutetium double phosphates has been performed to determine the energy levels in these hosts and to compare their optical behaviour with analogous sodium yttrium double phosphates. The emission and excitation spectra have been investigated using synchrotron radiation and the origin of the emission has been analysed proving that the emission occurs from the charge transfer state.

A Yb3+ -doped mixed-perovskite single crystal (La, Sr)(Al, Ta)O 3 (LSAT) crystal is grown by the Czochralski method. The absorption spectrum, fluorescence spectrum and fluorescence lifetime of Yb 3+ ions have been investigated, and the spectroscopic parameters of Yb:LSAT have also been calculated. This crystal exhibits a remarkably large ground-state splitting (about 1100 cm −1 ), a relatively long fluorescence lifetime (0.85 ms) and broad absorption and emission bandwidths. The results indicate that the Yb 3+ :LSAT crystal is a good candidate for diode-pumped ultrashort and tunable solid-state laser applications.

“…Nevertheless, knowledge about the CT luminescence is still rather limited. It was reported that systems containing the Lu 3ϩ ion instead of the Y 3ϩ ion, co-doped with ytterbium, seem to be even a better lattice for the lasing performance [13].…”

Abstract. Powder samples of the ternary phosphates A 3 Lu(PO 4 ) 2 :Yb 3ϩ (A ϭ Na, Rb) have been synthesised by solid state reactions. The spectroscopic properties of Yb 3ϩ in double phosphate host lattices were investigated using absorption, emission and excitation spectra at 4, 10 and 293 K in the VUV to IR range. The results obtained for both types of phosphates are compared. Together with the fundamental 2 F 5/2 Ǟ 2 F 7/2 emission in the IR range, a broad band emission with two peaks in the UV region Compounds containing Yb 3ϩ ions have potential applications as laser devices because of their simple electronic structure. There is no concentration quenching and no excited state absorption reducing the effective laser crossrelaxation process. The Yb 3ϩ ion exhibits intense and broad absorption bands in the IR region which is suitable for a diode-pumped laser. It was reported that ytterbium-doped lasers have longer emission lifetimes than the Nd 3ϩ -doped materials. All these properties of Yb 3ϩ indicate that the ytterbium-doped materials seem to be more promising than the neodymium-doped systems, already employed in laser materials. The fundamental luminescence of the Yb 3ϩ ion originating from the 2 F 5/2 Ǟ 2 F 7/2 transitions between the manifold of Stark-splitted levels occur in the IR range around 1000 nm.While searching for interesting laser host materials for solid state lasers, alkali rare-earth double phosphates of the M 3 RE(PO 4 ) 2 type were studied by several authors [1Ϫ10]. These compounds have their host absorption edge at a rather short wavelength which makes them suitable as host lattices for various luminescent materials.In addition to the intraconfigurational 4f-4f transitions, a broad emission band (called charge transfer band, CT) were observed in Yb 3ϩ -activated Na 3 Lu(PO 4 ) 2 . The second emission is due to a chargeϪtransfer transition type. The influence of the alkali metal cation site of the host lattice on the luminescence properties was investigated. The tentative energy level scheme of the ground and excited 2 F J (Jϭ7/2, 5/2) levels is described.
