“…Al-based melilites find applications in the field of optics. , In particular, adjustable optical properties can be obtained by proper doping with rare-earth , and substitutions on the A/B site. Also substitutions on the T 1 and T 2 sites are possible, which lead to the huge family of the Al–Si melilites.…”

Oxides characterized by a layered melilite structure, with general formula ABT 1(1) T 2(2) O 7 , find applications in many different technological fields due to their relevant magnetic, optical, and electrical properties. These functional properties are, in turn, related to local features such as structural defects and cation substitutions. Therefore, a complete structural characterization of these complex anisotropic compounds is mandatory, and the combined use of long-range (X-ray and neutron diffraction) and short-range (solid state NMR) techniques is a key approach to this aim. In this work, we present the full structural characterization of the series LaSrGa 3−x Al x O 7 (x = 0, 1, 1.5, 2, and 3), which was obtained for the first time by means of a new sol−gel approach. Analysis of neutron diffraction data revealed that the distribution of La/Sr and Ga/Al on the respective sites is random. 27 Al and 71 Ga solid state NMR enabled us to rationalize the local structure of the T sites in terms of nearest and next-nearest neighbors. This study provides a deep structural insight that can be helpful for the understanding of the functional properties and is a powerful strategy for the analysis of complex oxide systems.

“…Pracka et al 39 indicated value as high as 11 W m −1 K −1 for SLGM ͑SrLaGa 3 O 7 ͒ while Kushawaha et al 40 gave for SGGM ͑SrGdGa 3 O 7 ͒ a similar value than for YAG. A corresponds to calcium, strontium or barium cation, B is rare earth, yttrium, or scandium cation, and C corresponds to aluminum or gallium cation.…”

The effect of the ytterbium doping concentration could be modeled using a simple cationic mass difference model. For ytterbium content corresponding to an absorption coefficient of 10 cm −1 ͑or 85% absorption of the pump power͒ Yb: GdVO 4 ͑c-axis͒ and Yb: Gd 3 Ga 5 O 12 laser materials present the highest measured thermal conductivity values of 8.1 W belong to the 6 -7 W m −1 K −1 range while Yb: CaF 2 and Yb: Lu 2 SiO 5 are situated in the 5 -6 W m −1 K −1 range. Other matrices such as Yb: SrLaGa 3 O 7 , Yb: CaGdAl 3 O 7 , Yb: SrGdGa 3 O 7 , and Yb: BaLaGa 3 O 7 have thermal conductivity values lower than 5 W m −1 K −1 . With the knowledge of the thermal conductivities and the determination of the thermal expansion coefficients, thermal shock parameters are evaluated for several ytterbium doped laser hosts.

“…Moreover, because of the broad-band character of optical transitions, various upconversion mechanisms proceeding in rare-earth systems can be enhanced. The optical and laser properties of Nd 3+ , Pr 3+ , Er 3+ , Eu 3+ , Dy 3+ , Tm 3+ doped SrLaGa 3 O 7 [1][2][3][4][5][6][7][8] and Nd 3+ , Eu 3+ , Yb 3+ doped SrLaGaO 4 [1,6] have been reported. The spectroscopic data of Ho 3+ ions in SLG and SLO hosts have been presented in our recent works [9,10].…”
