Preparation and thermochromic property of tungsten-doped vanadium dioxide particles

The Memristive Properties of a Single VO2 Nanowire with Switching Controlled by Self‐Heating

“…During the heating and cooling cycles, the endothermic and the exothermic peaks that come from the transitions of M → R and R → M are observed at ≈68 and ≈59 °C, respectively, which is similar to the reported values of VO 2 . [ 15,17,28,29 ] This hysteretic behavior clearly shows that the VO 2 nanowires can exhibit the characteristic of the phase transition which is similar to that observed in VO 2 bulk. Figure 1 c shows the schematic of the single VO 2 nanowire-based memristor of which the two ends were electrically connected to copper wires with silver paste.…”

Solution Processing of Nanoceramic VO2 Thin Films for Application to Smart Windows

“…This decreasing efficiency is less than other reports. 36,38 Significantly, the decreasing efficiency of phase transition temperature for 1 at % W-doped film was lower than the average efficiencies of other doping doses in references, which employed similar doping process to prepare VO 2 particles, 81 probably because the tungsten ion was not completely incorporated into the final VO 2 films. W4f 5/2 and W4f 7/2 XPS peaks with a binding energy of 37.7 and 35.3 eV, respectively, are clearly seen in Figure 11b inset for the W-doped thin films and the tungsten ion in these films is W 6+ according to the standard binding energy.…”

Nanothermochromics: Calculations for VO2 nanoparticles in dielectric hosts show much improved luminous transmittance and solar energy transmittance modulation

“…56 The incorporation of VO 2 in polymer matrices 57,58 has been demonstrated too. Nanoparticles of VO 2 with more or less symmetrical shapes have been made by wet chemistry, [59][60][61][62][63][64][65][66] 74 There are also numerous works on nanorods ͑nanowires͒ of VO 2 prepared by wet chemistry, [75][76][77][78][79][80][81][82] gas phase synthesis, 32,[83][84][85][86][87][88][89] ion implantation of vanadium and oxygen ions followed by annealing, [27][28][29]90 and by thermal oxidation of V; 33,91 these particles can be represented as higheccentricity prolate particles. VO 2 : W nanorods have been deposited by wet chemistry 92 and VO 2 : Mo nanorods have been made by a sol-gel based technique.…”
