Thermochemical and luminescent properties of RbVO3, CsVO 3, and Rb0.5Cs0.5VO3

RbVO3, CsVO3, and Rb0.5Cs 0.5VO3 have been synthesized by the Pechini process. The vanadates have an orthorhombic structure (sp. gr. Pbcm), melt congruently in the range 650-530°C, and undergo a reversible phase transition in the range 520-340°C. We have determined the onset temperatures and end points of the transformations at a temperature scan rate of 3°C/min and their enthalpies, and measured the photo-, roentgeno-, and cathodoluminescence and diffuse reflectance spectra of the vanadates. The luminescence spectra each are well fitted with three pseudo-Voigt functions. CsVO3 has the highest integrated emission intensity. The emission intensity of the Rb 0.5Cs0.5VO3 solid solution is lower than that of the simple vanadates because of the optical absorption around its intrinsic luminescence band. This may be due to the presence of stable vacancy-type structural defects in Rb0.5Cs0.5VO3.

Synthesis, structures and magnetic properties of the new vanadates AgMnVO4 and RbMnVO4

The new compounds, AgMnVO4 and RbMnVO4 have been synthesized by solid state reaction route. Their crystal structures were determined from single-crystal X-ray diffraction data for RbMnVO4 and powder X-ray diffraction data for AgMnVO4. AgMnVO4 crystallizes with the maricite-type structure in space group Pnma, a=9.5778(6) A, b=6.8518(4) A, c=5.3734(3) A and Z=4. RbMnVO4 crystallizes in space group P63 with a stuffed tridymite-type structure, a=11.2584(3), c=8.9893(13) A and Z=8. A merohedral twinning was taken into account for its structural refinement. To our knowledge this is the first vanadate showing this structural type. AgMnVO4 and RbMnVO4 were characterized by magnetic susceptibility and specific heat measurements. AgMnVO4 is antiferromagnetic with a Neel temperature of 12.3 K determined by specific heat measurements. RbMnVO4 exhibits canted antiferromagnetism with a Neel temperature of 6.5 K.

A3V5O14 (A = K+, Rb +, or Tl+), New polar oxides with a tetragonal tungsten bronze related structural topology: Synthesis, structure, and functional properties

Three polar noncentrosymmetric (NCS) oxide materials, A3V 5O14 (A = K+, Rb+, or Tl +), have been synthesized by hydrothermal and conventional solid state techniques. Their crystal structures and functional properties (second-harmonic generation, piezoelectricity, and polarization) have been determined. The iso-structural materials exhibit a layered structural topology that consists of corner-sharing VO4 tetrahedra and VO5 square pyramids. The layers stack parallel to the c-axis direction and are separated by the K+, Rb+, or Tl+ cations. Powder second-harmonic generation (SHG) measurements using 1064 nm radiation indicate the materials exhibit moderate SHG efficiencies of ～100× α-SiO2. Additional SHG measurements, that is, particle size versus SHG efficiency, indicate the materials are type-I phase-matchable. Converse piezoelectric measurements for K3V5O 14, Rb3V5O14, and Tl 3V5O14 revealed d33 values of 28, 22, and 26 pm/V, respectively. Pyroelectric measurements, that is, temperature-dependent polarization measurements, resulted in pyroelectric coefficients of -2.2, -2.9, and -2.8 μC/m2K at 65 °C, for K3V5O14, Rb3V5O 14, and Tl3V5O14 respectively. Frequency-dependent polarization measurements confirmed that all of the materials are nonferroelectric, consistent with our first principle density functional theory (DFT) electronic structure calculations. Infrared, UV-vis, thermogravimetric, and differential scanning calorimetry measurements were also performed. Crystal data: K3V5O14, trigonal, space group P31m (No. 157), a = 8.6970(16) A, c = 4.9434(19) A, V = 323.81(15), and Z = 1; Rb3V5O14, trigonal, space group P31m (No. 157), a = 8.7092(5) A, c = 5.2772(7) A, V = 346.65(5), and Z = 1; Tl3V5O14, trigonal, space group P31m (No. 157), a = 8.7397(8) A, c = 5.0846(10) A, V = 336.34(8), and Z = 1.

Improvement of luminescence properties of rubidium vanadate, RbVO3, phosphors by erbium doping in the crystal lattice

Greenish-white emitting Rb1-xErxVO3 (0 ≤ x ≤ 0.10) phosphors were synthesized by a conventional solid state reaction method. The thermal quenching effect of the RbVO3 phosphors was effectively improved by Er3+ doping into the RbVO3 lattice. Consequently, the emission peak intensity of the phosphors was successfully enhanced by Er3+ doping, and the internal quantum efficiency of Rb0.99Er0.01VO3 under excitation at 360 nm was 80%.

On a rubidium cadmium oxovanadate(V) showing a tunnel structure: RbCd3(VO4)(V2O7)

Coulorless single crystals of RbCd3(VO4)(V2O7) have been prepared by heating of RbVO3, CdO and V2O5 in closed steel tubes. It shows monoclinic symmetry, space group C52h-P21/c, a = 8.397(2), b = 9.775(2), c = 12.616(2) ?, β = 98.50(2)°, Z = 4. Despite the similarity of the chemical composition to other oxovanadates(V) RbCd3(VO4)(V2O7) form a new structure type, characterized by a [Cd3V3O11] network made up from CdO6 octahedra, VO4 tetrahedra and V2O7 divanadate groups. Typical features are edge shared [Cd3O13] units and the edge bridging of two CdO6 octahedra by one V2O7 group.

The diphyllosilicate Rb2(VO)2[Si8O 19]

Dirubidium divanadyl phylloocta-silicate, Rb2(VO)2[Si8O19], is the first known anhydrous diphyllosilicate containing VIV. The structure consists of silicate double layers which are separated by [V2O8]8- dimers and is related to that of the compounds A 2Cu2[Si8O19] (A = Rb or Cs), although the title compound crystallizes in a noncentrosymmetric ortho-rhom-bic space group. The silicate double layers contain four tetra-hedrally coordinated Si sites in general positions and 12 O sites, nine in general positions and the other three on mirror planes. The vanadyl dimers have two square-pyramidally coordinated V sites (site symmetry m). There are two different 10- and 12-fold coordinated Rb sites with site symmetry m, one of which is a split position located between the dimers in the inter-layer space, while the other is in a channel within the silicate layer.
