Abstract

The low temperature spectroscopic properties of Mn ⁴⁺ (3d ³) in the orthorhombic perovskite, LaInO ₃, is examined in this work. The exchange charge model of crystal-field theory is used to calculate the Mn ⁴⁺ energy levels. The spectra can be fitted by the parameters D q = 1776 cm ^–1, B = 700 cm ^–1 and C = 3189 cm ^–1, with C/B = 4.5. Discussions pertaining to the low luminescence efficiency of LaInO ₃:Mn ⁴⁺ are presented. A comparative study of the variations in the energy of the ²E _g → ⁴A _2g emission transition in a series of materials with the perovskite structure is presented. Here, the data suggest a relationship between the energy of the ²E _g → ⁴A _2g emission transition and the deviation of the octahedral O-Mn-O bond angle from the ideal 90°. It is concluded that the angular distortion is not large enough to support the development of high luminosity Mn ⁴⁺ activated phosphors in the ABO ₃ perovskite family of materials.

Optical Properties of Two-Dimensional Perovskite Films of (C ₆H ₅C ₂H ₄NH ₃) ₂[PbI ₄] and (C ₆H ₅C ₂H ₄NH ₃) ₂(CH ₃NH ₃) ₂[Pb ₃I ₁₀]

Journal Article Zhang, Yang ; Wang, Ruizhi ; Li, Yezhou ; ... - Journal of Physical Chemistry Letters

The temperature dependence of absorption and photoluminescence (PL) spectroscopies were used to study the optical properties of 2D perovskite films, including n = 1 and 3 of (PEA) ₂(CH ₃NH ₃) _n-1[Pb _nI _3n+1] (PEA = C ₆H ₅(CH ₂) ₂NH ₃). In (PEA) ₂[Pb ₁I ₄] (PEPI), excitons coupling to optical phonons with an average energy of ~30 meV dominate the photophysics of absorption and PL. (PEA) ₂(CH ₃NH ₃) ₂[Pb ₃I ₁₀] (shortened as PMPI ₃), nominally prepared as n = 3, actually was a mixture of multiple layered perovskites with various n. In absorption, a PMPI ₃more »« less

Spin gaps in the ordered states of ${La}_{2} Li X O_{6} (X = Ru, Os)$ and their relation to the distortion of the cubic double perovskite structure in $4 d^{3}$ and $5 d^{3}$ magnets

Journal Article Maharaj, D. D. ; Sala, G. ; Marjerrison, C. A. ; ... - Physical Review B

Time-of-flight inelastic neutron scattering measurements have been carried out on polycrystalline samples of the 4d ³ and 5d ³ double pervoskite antiferromagnets La ₂LiRuO ₆ and La ₂LiOsO ₆. These reveal the development of an inelastic spin gap in La ₂LiRuO ₆ and La ₂LiOsO ₆ of ~1.8(8) and 6(1) meV, below their respective ordering temperatures TN, ~23.8 and 30 K. The bandwidths of the spin excitations are shown to be ~5.7(9)and12(1)meV, respectively, at low temperatures. Spin gaps are surprising in such magnets as the t _2g levels of Ru ⁵⁺ or Os ⁵⁺ are expected to be half-filled, resultingmore »« less

Effect of the Mn{sup 3+} ion on electrical and magnetic properties of orthorhombic perovskite-type Ca(Mn{sub 1-x}Ti {sub x})O{sub 3-{delta}}

Journal Article Nakade, Katsuyuki ; Hirota, Ken ; Kato, Masaki ; ... - Materials Research Bulletin

Orthorhombic perovskite-type Ca(Mn{sub 1-x}Ti {sub x})O{sub 3-{delta}} (0 {<=} x {<=} 0.7) was synthesized at 1173 K for 12 h in a flow of oxygen from a precursor gel prepared using citric acid and ethylene glycol. The Mn{sup 3+} ion was generated by substituting a Ti{sup 4+} ion in CaMnO{sub 3}. The average particle size was 100-300 nm and did not depend on x. The lattice constants and the (Mn, Ti)-O distance increased linearly with increasing x. The variation in global instability index (GII) indicated that the instability of the structure increases monotonically with increasing x. Ca(Mn{sub 1-x}Ti {sub x})O{submore »« less

Redox chemistry of a binary transition metal oxide (AB ₂ O ₄ ): a study of the Cu ²⁺ /Cu ⁰ and Fe ³⁺ /Fe ⁰ interconversions observed upon lithiation in a CuFe ₂ O ₄ battery using X-ray absorption spectroscopy

Journal Article Cama, Christina A. ; Pelliccione, Christopher J. ; Brady, Alexander B. ; ... - Physical Chemistry Chemical Physics. PCCP (Print)

Copper ferrite, CuFe ₂ O ₄, is a promising candidate for application as a high energy electrode material in lithium based batteries. Mechanistic insight on the electrochemical reduction and oxidation processes was gained through the first X-ray absorption spectroscopic study of lithiation and delithiation of CuFe ₂ O ₄. A phase pure tetragonal CuFe ₂ O ₄ material was prepared and characterized using laboratory and synchrotron X-ray diffraction, Raman spectroscopy, and transmission electron microscopy. We used ex situ X-ray absorption spectroscopy (XAS) measurements to study the battery redox processes at the Fe and Cu K-edges, using X-ray absorption near-edge structuremore »« less

Magnetic properties of double perovskite $L n_{2} {CoIrO}_{6}$ $(L n = Eu, Tb, Ho)$ : Hetero-tri-spin $3 d - 5 d - 4 f$ systems

Journal Article Ding, Xiaxin ; Gao, Bin ; Krenkel, Elizabeth ; ... - Physical Review B

The field of double perovskites is now advancing to three magnetic elements on the A, B and B' sites. A series of iridium-based double perovskite compounds, Ln ₂ CoIrO ₆ (Ln = Eu, Tb, Ho), with three magnetic elements was synthesized as polycrystalline samples. The compounds crystalize in monoclinic structures with the space group P2 ₁/n. Magnetic properties of these hetero-tri-spin 3 d-5 d-4 f systems were studied by magnetic susceptibility and field dependent magnetization in both DC and pulsed magnetic fields. All these compounds show ferrimagnetic transitions at temperatures T C above 100 K, which are attributable to antiferromagneticmore »« less
