Synthesis, structural characterization and optical properties of a new cesium aluminum borate, Cs2Al2B2O7

AbstractA new borate, Cs2Al2B2O7, was synthesized by solid-state reaction. It crystallizes in the monoclinic space group P21/c with a=6.719(1) Å, b=7.121(1) Å, c=9.626(3) Å, β=115.3(1)°, and Z=2. In the structure, two AlO4 tetrahedra and two BO3 planar triangles are connected alternately by corner-sharing to from nearly planar [Al2B2O10] rings, which are further linked via common O1 atom to generate layers in the bc plane. These layers then share the O3 atoms lying on a center of inversion to form a three-dimensional framework with Cs atoms residing in the channels. The IR spectrum confirms the presence of both BO3 and AlO4 groups and the UV–vis–IR diffuse reflectance spectrum indicates a band gap of about 4.13(2) eV.

Rare-earth transition-metal chalcogenides Ln3MGaS7 (Ln=Nd, Sm, Dy, Er; M=Co, Ni) and Ln3MGaSe7 (Ln=Nd, Sm, Gd, Dy, M=Co; Ln=Nd, Gd, Dy, M=Ni)

Highlights•New compounds, Ln3MGaQ7 (Ln=rare-earth; M=Co, Ni; Q=S, Se), were synthesized.•They are isostructural and crystallize in the noncentrosymmetric space group P63.•They adopt a three-dimensional framework built by LnQ7 monocapped trigonal prisms.•Ln3CoGaQ7 (Ln=Dy, Er; Q=S, Se) are paramagnetic and obey the Curie–Weiss law.•The magnetic susceptibility of Sm3CoGaSe7 deviates from the Curie–Weiss law.

Quaternary rare-earth sulfides Nd7FeInS13 and Pr7CoInS13

Highlights•Nd7FeInS13 and Pr7CoInS13 are new quaternary phases in RE–M–In–S systems.•The structure contains chains of FeS4 or CoS4 tetrahedra, and of InS6 octahedra.•Pr7CoInS13 exhibits paramagnetic behaviour down to 2 K.

Quaternary rare-earth selenides Ba2REGaSe5 and Ba2REInSe5

Highlights•Twelve new quaternary chalcogenides Ba2REMSe5 (M = Ga, In) were prepared.•A structure map effectively separates different structures found in Ba2REMCh5.•The limits of formation are defined by avoidance of overbonding of RE atoms.•Ba2REGaSe5 separates into two structural branches depending on size of RE.

Fabrication, microstructure and optical properties of large-sized Nd:YAG and composite Yb:YAG transparent ceramic slabs

AbstractLarge-sized Nd:YAG and composite Yb:YAG transparent ceramic slabs of high quality were fabricated by the conventional solid-state reaction sintering technique. The Yb:YAG transparent ceramic slabs were surrounded by undoped YAG transparent ceramics and this composite structure was built in the process of ceramic shaping. The difference in microstructure between Yb:YAG and YAG transparent ceramics was not observed and the composite Yb:YAG slabs showed fully dense and pore-free microstructure. The in-line transmittances at 400 nm reached 81.7% and 79.7 % for YAG and Yb:YAG transparent ceramics, respectively, indicating good optical quality of the composite ceramic slab. And the optical transmission micrograph was very homogeneous with only a few isolated scattering centers. These results suggested that building composite structure in the process of ceramic shaping was a simple and reliable technical scheme. Moreover, the large-sized Nd:YAG transparent ceramic slab with size of 150.0 mm × 50.0 mm × 4.0 mm was also prepared. The calculated absorption coefficient was about 0.002 cm-1 @1064 nm, which suggested that the optical quality of this Nd:YAG transparent ceramic slab had reached the level of Nd:YAG crystals.
