A vanadium dioxide display tube

1972 International Electron Devices Meeting, 1972
Vanadium dioxide is shown to be, useful as a display medium in electron tubes with applicability as large area displays, storage tubes and "page composers". The utility of VO 2 in this role is a consequence of the large decrease in the index of refraction at 67°C.

Magnetic Susceptibility of Vanadium Dioxide

Nature, 1954
WE have found that the reduction of vanadium pentoxide (V2O5) as described below gives a form of vanadium oxide (VO2) which has not the magnetic discontinuity (at 341° K.) reported in the literature1,2.

Crystal growth of vanadium dioxide

Materials Research Bulletin, 1970
Abstract The phase diagram of the V-O system at 1500°K has been re-examined (mainly in the VO2 region) and vanadium dioxide crystals have been grown from vanadium pentoxide (M.P. about 950°K) under various oxygen partial pressures. The total pressure was one atm. The chemical analyses of these oxides indicated the stability range of VO2+x from x=0.00

A New Vanadium Dioxide Cathode

Journal of The Electrochemical Society, 1996
We have synthesized a new form of vanadium dioxide using the hydrothermal reaction of vanadium pentoxide and lithium hydroxide in the presence of an organic templating cation. The hydrated lithium vanadium oxide formed has the simplest layered structure of any vanadium oxide, containing only VO 5 square pyramids whose apices alternate up and down in ...

Switchable absorber by vanadium dioxide

2016 15th International Conference on Optical Communications and Networks (ICOCN), 2016
In this paper we numerically simulate a broadband absorber made of Al 2 O 3 and phase transition material vanadium dioxide (VO 2 ). Its structure consists of three layers: VO 2 grating array, Al 2 O 3 film, and VO 2 film at the bottom. As temperature increasing from 30°C to 85°C, VO 2 varies from the insulator to metal phase.

Electrochemically Induced Transformations of Vanadium Dioxide Nanocrystals

Nano Letters, 2016
Vanadium dioxide (VO2) undergoes significant optical, electronic, and structural changes as it transforms between the low-temperature monoclinic and high-temperature rutile phases. Recently, alternative stimuli have been utilized to trigger insulator-to-metal transformations in VO2, including electrochemical gating.

Ellipsometric investigation of vanadium dioxide films

Journal of Applied Physics, 1985
Vanadium dioxide undergoes a transition at about 68 °C where the physical properties of the oxide, in particular the index of refraction and possibly the density, abruptly change values. In this work the indices of refraction of thermally grown films of vanadium dioxide on a vanadium substrate have been determined at room temperature and at 84 °C using

Vanadium Dioxide Storage Material

Optical Engineering, 1981
Vanadium dioxide undergoes a semiconductor-metal phase transi­ tion at temperature of 340 K. When prepared as a thin film on a suitable substrate, the transition exhibits hysteresis, i.e. the curve describing the state of the film versus temperature is double valued. Here the material is capable of existing in equilibrium in either of two states at the

Synthesis of vanadium dioxide thin films from vanadium alkoxides

Materials Research Bulletin, 1994
Abstract A very simple sol-gel route to vanadium dioxide thin films is described. Vanadium alkoxide molecular precursors are deposited onto a fused silica substrate by the spin coating technique. An amorphous thin film is obtained at room temperature which leads to crystalline VO 2 when heated at 450°C under a reducing atmosphere (Ar 2 ).
