Crystal Structure Dependence of the Energy Transfer from Tb(III) to Yb(III) in Metal–Organic Frameworks Based in Bispyrazolylpyridines

Crystals, 2020
Luminescent mixed lanthanide metal−organic framwork (MOF) materials have been prepared from two polyheterocyclic diacid ligands, 2,6-bis(3-carboxy-1-pyrazolyl)pyridine and 2,6-bis(4-carboxy-1-pyrazolyl)pyridine.

Redetermination of the crystal structure of yttrium chromium tetraboride, YCrB4, from single-crystal X-ray diffraction data

Acta Crystallographica Section E: Crystallographic Communications, 2023
The structural parameters of yttrium chromium tetraboride YCrB4 were refined based on single-crystal X-ray diffraction data. YCrB4 is orthorhombic, having a space group of type Pbam (No. 55) and with lattice parameters of a = 5.9425 (2), b = 11.4831 (4),

A multistep single-crystal-to-single-crystal bromodiacetylene dimerization

Nature Chemistry, 2013
Packing constraints and precise placement of functional groups are the reason that organic molecules in the crystalline state often display unusual physical or chemical properties not observed in solution. Here we report a single-crystal-to-single-crystal dimerization of a bromodiacetylene that involves unusually large atom displacements as well as the

Syntheses and structures of ammonium transition-metal dialuminium tris(phosphate) dihydrates (NH4)MAl4(PO4)3·2H2O (M = Mn and Ni)

Acta Crystallographica Section E: Crystallographic Communications, 2023
The structures of ammonium manganese(II) dialuminium tris(phosphate) dihydrate, (NH4)MnAl2(PO4)3·2H2O, and ammonium nickel(II) dialuminium tris(phosphate) dihydrate, (NH4)NiAl2(PO4)3·2H2O, were determined using single-crystal diffraction data.

Crystal Growth of Single Salicylamide Crystals [PDF]

Crystal Growth & Design, 2019
Growth of single salicylamide crystals was investigated in a nonstirred growth cuvette and on a rotating disk. In the growth cuvette the crystal growth rates were measured for both primary nucleated crystals and seed crystals manually inserted into the cuvette.

Single-crystal two-dimensional material epitaxy on tailored non-single-crystal substrates

Nature Communications, 2022
The heteroepitaxial growth of crystalline 2D materials is usually based on single-crystal substrates. Here, the authors demonstrate that single-crystal graphene and hexagonal boron nitride films can be successfully grown on wafer-scale copper foils with ...

New insights into the recrystallization behavior of large-size Mo–3Nb single crystal based on multi-scale characterization

Journal of Materials Research and Technology, 2022
The occurrence of recrystallization will cause catastrophic damage to the structure of metallic single crystal, which can be avoided by choosing crystal orientation reasonably.

Optical Spectra Properties and Continuous-Wave Laser Performance of Tm,Y:CaF2 Single Crystals

International Journal of Optics, 2018
3 at.% Tm, x at.% Y:CaF2 crystals (x=0, 0.5, 1, 2, and 3) were grown by the vertical Bridgman method and investigated. Codoping Y3+ ions can manipulate the local structure of Tm3+ ions in the CaF2 crystal and then improve the spectroscopic properties ...
