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.

Single Crystal to Single Crystal Transformations [PDF]

Australian Journal of Chemistry, 2006
The past decade has witnessed escalating interest in solidstate phase transitions that involve significant changes in structure without appreciable loss of crystal mosaicity— single crystal to single crystal (SC-SC) transformation.[1–5] Several factors have contributed to these studies: increased general access to X-ray diffraction facilities ...

Room temperature continuous wave operation of single-mode, edge-emitting photonic crystal Bragg lasers [PDF]

, 2008
We report the first room temperature CW operation of two dimensional single-mode edge-emitting photonic crystal Bragg lasers. Single-mode lasing with single-lobed, diffraction limited far-fields is obtained for 100μm wide and 550μm long on-chip devices ...

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),

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 ...
