Valence States in CeVO4 and Ce0.5Bi0.5VO4 Probed by Density Functional Theory Calculations and X-ray Photoemission Spectroscopy
(2014)Ce is one of the few lanthanide elements to exhibit well-defined (III) and (IV) oxidation states in solid state environments and there is therefore ambiguity as to whether CeVO4 should be formulated as Ce(III)V(V)O4 or ... -
Valence-band density of states and surface electron accumulation in epitaxial SnO2 films
(2014)The surface band bending and electronic properties of SnO 2 (101) films grown on r -sapphire by plasma-assisted molecular beam epitaxy have been studied by Fourier-transform infrared spectroscopy (FTIR), x-ray ... -
Variable-height scanning tunneling spectroscopy for local density of states recovery based on the 1D-WKB approximation
(2010)We introduce a variable-height scanning tunneling spectroscopy (VH-STS) method that provides a good level of recovery of the combined surface and tip density of states (DOS) in any bias range without the complexity of ... -
Vibrational characterization of different benzene phases on flat and vicinal Si(100) surfaces
(2007-10-17)Based on high-resolution electron energy loss spectroscopy and temperature-programmable desorption, benzene chemisorption on vicinal and nominally flat Si 100 surfaces has been studied for various adsorption, annealing, ... -
Visible light-harvesting trans bis(alkylphosphine) platinum(II)-alkynyl complexes showing long-lived triplet excited states as triplet photosensitizers for triplet-triplet annihilation upconversion
(2013)Symmetric and asymmetric linear trans-bis(tributylphosphine) Pt(II) bis(acetylide) complexes with functionalized aryl alkynyl ligands (coumarin, naphthalimide and phenyl acetylides) were prepared, which show enhanced ... -
Water-soluble, neutral 3,5-diformyl-BODIPY with extended fluorescence lifetime in a self-healable chitosan hydrogel
(2017)3,5-Diformyl-4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (3,5-diformyl-BODIPY) can be used as an efficient biofunctional cross-linker to generate a new class of chitosan-based hydrogels with fluorescence resonance energy ... -
Weak Interactions and Conformational Changes in Core-Protonated A 2- and A x-Type Porphyrin Dications
(2020)Individual chemical motifs are known to introduce structural distortions to the porphyrin macrocycle, be it in the core or at the periphery of the macrocycle. The interplay when introducing two or more of these known ... -
White-light emission from discrete heterometallic lanthanide-directed self-assembled complexes in solution
(2017)White-light-emitting materials have attracted significant interest in recent years due to their potential applications in solid-state lighting and flat-panel displays. Design of such materials is challenging and often ... -
An X-ray absorption and photoemission study of the electronic structure of Ni porphyrins and Ni N-confused porphyrin
(2008)Investigations of chemical bonding and electronic structure features for polycrystalline (porphyrinato)nickel (II) (NiP, the simplest Ni porphyrin), (5,10,15,20-tetraphenylporphyrinato)nickel (II) (NiTPP) and (2-aza-2 ... -
X-ray spectroscopic study of the electronic structure of CuCrO2
(2009)The electronic structure of the p-type transparent conducting oxide CuCrO2 has been studied by x-ray photoemission, x-ray absorption, and x-ray emission spectroscopies. The upper part of the valence band derives mainly ...
