  • Vanadium dioxide (VO{sub 2}) is known to have a semiconductor-to-metal phase transition at ∼68 °C. Therefore, it can be used as a tunable component of an active metamaterial. The lamellar metamaterial studied in this work is composed of subwavelength VO{sub 2} and Au layers and is designed to undergo a temperature controlled transition from the optical hyperbolic phase to the metallic phase. VO{sub 2} films and VO{sub 2}/Au lamellar metamaterial stacks have been fabricated and studied in electrical conductivity and optical (transmission and reflection) experiments. The observed temperature-dependent changes in the reflection and transmission spectra of the metamaterials and VO{sub 2}more » thin films are in a good qualitative agreement with theoretical predictions. The demonstrated optical hyperbolic-to-metallic phase transition is a unique physical phenomenon with the potential to enable advanced control of light-matter interactions.« less
  • Hydrothermal reaction of VCl{sub 4} with phosphorous acid H{sub 3}PO{sub 3}, in the presence of organoamines, yields oxovanadium (IV)-phosphite materials: [HN(Me)(CH{sub 2}CH{sub 2}){sub 2}N(Me)H][(VO){sub 4}(OH){sub 2}-(HPO{sub 3}){sub 4}] (1), [H{sub 2}N(CH{sub 2}CH{sub 2}){sub 2}NH{sub 2}][(VO){sub 3}(HPO{sub 3}){sub 4}-(H{sub 2}O){sub 2}] (2), and [VO(HPO{sub 3})H{sub 2}O] (3). The framework structure of 3 is presented. 32 refs., 3 figs.
  • New uranyl vanadates A{sub 3}(UO{sub 2}){sub 7}(VO{sub 4}){sub 5}O (M=Li (1), Na (2), Ag (3)) have been synthesized by solid-state reaction and their structures determined from single-crystal X-ray diffraction data for 1 and 3. The tetragonal structure results of an alternation of two types of sheets denoted S for {sub {infinity}}{sup 2}[UO{sub 2}(VO{sub 4}){sub 2}]{sup 4-} and D for {sub {infinity}}{sup 2}[(UO{sub 2}){sub 2}(VO{sub 4}){sub 3}]{sup 5-} built from UO{sub 6} square bipyramids and connected through VO{sub 4} tetrahedra to {sub {infinity}}{sup 1}[U(3)O{sub 5}-U(4)O{sub 5}]{sup 8-} infinite chains of edge-shared U(3)O{sub 7} and U(4)O{sub 7} pentagonal bipyramids alternatively parallel tomore » a- and b-axis to construct a three-dimensional uranyl vanadate arrangement. It is noticeable that similar {sub {infinity}}[UO{sub 5}]{sup 4-} chains are connected only by S-type sheets in A{sub 2}(UO{sub 2}){sub 3}(VO{sub 4}){sub 2}O and by D-type sheets in A(UO{sub 2}){sub 4}(VO{sub 4}){sub 3}, thus A{sub 3}(UO{sub 2}){sub 7}(VO{sub 4}){sub 5}O appears as an intergrowth structure between the two previously reported series. The mobility of the monovalent ion in the mutually perpendicular channels created in the three-dimensional arrangement is correlated to the occupation rate of the sites and by the geometry of the different sites occupied by either Na, Ag or Li.

  • An ultrafast and low-power all-optical tunable metamaterial-induced transparency is realized, using polycrystalline barium titanate doped gold nanoparticles and multilayer tungsten disulfide microsheets as nonlinear optical materials. Large nonlinearity enhancement is obtained associated with quantum confinement effect, local-field effect, and reinforced interaction between light and multilayer tungsten disulfide. Low threshold pump intensity of 20 MW/cm{sup 2} is achieved. An ultrafast response time of 85 ps is maintained because of fast carrier relaxation dynamics in nanoscale crystal grains of polycrystalline barium titanate. This may be useful for the study of integrated photonic devices based on two-dimensional materials.
  • Two new layered vanadium phosphates, (H[sub 2]NC[sub 4]H[sub 8]NH[sub 2])[(VO)[sub 2](PO[sub 4])[sub 2]] (1) and (H[sub 2]NC[sub 4]H[sub 8]NH[sub 2])[sub 2][(VO)[sub 3](HPO[sub 4])[sub 2](PO[sub 4])[sub 2]][center dot]H[sub 2]O (2), have been hydrothermally synthesized under similiar conditions. Compound 1 is synthesized from VCl[sub 4], H[sub 3]PO[sub 4], piperazine, (n-C[sub 4]H[sub 9])[sub 4]NOH, and H[sub 2]O in the mole ratio 1:2.7:2.1:1.2:350 at 200 [degrees]C for 70 h and autogeneous pressure. In contrast, the preparation of 2 required the presence of (CH[sub 3])PO[sub 3]H[sub 2], such that reaction of VCl[sub 4], H[sub 3]PO[sub 4], (CH[sub 3])PO[sub 3]H[sub 2], piperazine (n-C[sub 4]H[sub 9])[sub 4]NOH,more » and H[sub 2]O in the mole ratio 1:3.5:1.2:3.3:1.2:390 at 200 [degrees]C for 70 h yields 2 in 50% yield, with 1 as the other component. Green plates of compound 1 crystallize in the monoclinic space group P2[sub 1]/c with a = 8.786(2) [angstrom], b = 8.257(2) [angstrom], c = 8.566(2) [angstrom], [beta] = 111.07(3)[degrees], V = 579.9(3) [angstrom][sup [minus]3], Z = 2, and R = 0.0298 whereas blue plates of 2 crystallize in the noncentrosymmetric orthorhombic space group Pna2[sub 1] with a = 14.631(3) [angstrom], b = 8.706(2) [angstrom], c = 17.635(4) [angstrom], V = 2246.3(11) [angstrom][sup [minus]3], Z = 4, and R = 0.0363. Compound 1 has puckered layers containing triangular bipyramidal vanadium(IV) centers. Phosphate 2 has VOPO[sub 4[minus]] like layers with 1/4 of the V(IV) octahedral sites missing which results in unusual edge-sharing involving half the phosphate tetrahedral with the vanadium octahedra and protonation of the remaining phosphate groups to give HPO[sub 4[sup 2[minus]]] residues.« less
