“…Concretely, both samples display broad features in the 20-60 eV past the edge, which are signatures of octahedral molecular resonances A1g, T2g, and Eg. 43 This confirms that a large population of [TeBr6] 2octahedral complex anions are stabilized in this ink, as corroborated by the UV-visible absorption data. Furthermore, the ink spectrum also contains a stronger pre-edge feature than the Cs2TeBr6 standard, which indicates the presence of anisotropic complexes.…”

“…Comparison of the Cs 2 TeBr 6 –DMSO ink to the Cs 2 TeBr 6 powder standard sample displays a similar white line feature as well as other spectral similarities (Figure a). Concretely, both samples display broad features in the 20–60 eV past the edge, which are signatures of octahedral molecular resonances A 1g , T 2g , and E g . This confirms that a large population of [TeBr 6 ] 2– octahedral complex anions are stabilized in this ink, as corroborated by the UV–visible absorption data.…”

“…Different coordination environments around the Te-center affect its energy transition probed through XANES. For example, a strong white line feature has previously been associated with an electron excitation to the E g molecular orbital in [PtCl 6 ] 2– octahedral complexes measured in Cs 2 PtCl 6 powders . Comparison of the Cs 2 TeBr 6 –DMSO ink to the Cs 2 TeBr 6 powder standard sample displays a similar white line feature as well as other spectral similarities (Figure a).…”

Ligand-Free Processable Perovskite Semiconductor Ink

Traditional covalent semiconductors require complex processing methods for device fabrication due to their high cohesive energies. Here, we develop a stable, ligand-free perovskite semiconductor ink that can be used to make patterned semiconductor-based optoelectronics in one step. The perovskite ink is formed via the dissolution of crystals of vacancy-ordered double perovskite Cs2TeX6 (X = Cl -, Br -, I -) in polar aprotic solvents, leading to the stabilization of isolated [TeX6] 2octahedral anions and free Cs + cations without the presence of ligands. The stabilization of the fundamental perovskite ionic octahedral building blocks in solution creates multi-functional inks with the ability to reversibly transform between the liquid ink and the solidstate perovskite crystalline system in air within minutes. These easily processable inks can be patterned onto various materials via dropcasting, stamping, and spraying or painting, highlighting the crucial role of solvated octahedral complexes towards rapid formation of phasepure perovskite structures in ambient conditions.

Remnant X-ray Magnetic Circular Dichroism Investigation of the Local Magnetic Contributions to the Magnetization of a Coercive Bimetallic Molecule-Based Magnet

2004

X-ray magnetic circular dichroism (XMCD) measurements have been performed at the Cr and Fe K-edges for the two-dimensional oxalate-based magnet {[N(C 4 H 9 ) 4 ][Fe II Fe III 0.77 Cr III 0,23 (oxin its long-range ordered magnetic state. First, the XMCD spectra recorded under a 2 T applied magnetic field are used to probe the local exchange interaction between the metal ions through the relative orientation of their spins in the magnetic field. The remnant local magnetic moments on the Cr and Fe ions have been clearly evidenced, analyzed, and compared to the total remnant magnetization measured by conventional magnetometry. The respective impact of single ion anisotropy, magneto-structural anisotropy, and exchange interaction on the remnant magnetic state is then discussed.
