Optical characterization of vanadium–titanium oxide films

Crystallised mesoporous TiO2(A)–VO2(M/R) nanocomposite films with self-cleaning and excellent thermochromic properties

“…Methods are available to obtain single-layered TiO 2 (A)-VO 2 by simultaneously depositing TiO 2 and VO 2 at a critical temperature [26][27][28][29] but the diffusion of Ti atoms into VO 2 crystal lattices weakens the thermochromic performance of VO 2 . 26,30 Because the crystallisation temperature of TiO 2 (A) is much lower than that of VO 2 (R), 31 a workable method for TiO 2 (A) & VO 2 single-layered composite lms could be the "two-step method", in which VO 2 nanoparticles (NPs) are rst prepared and dispersed in titanium sol to form a composite lm and then annealed for TiO 2 crystallisation. This method largely restricts Ti diffusion and maintains the thermochromic performance of VO 2 .…”

A Review of Vanadium Dioxide as an Actor of Nanothermochromism: Challenges and Perspectives for Polymer Nanocomposites

“…Doping by cations of small sizes and valences less than or equal to that of V leads to higher transition temperatures at 68°C. For instance, an increase of T c is observed with M being Ge(+IV), [70] Al(+III), [81] Sn(+IV), [82] Ti(+IV), [83] or Sb(+III). [71] Various efforts have been conducted to study the effects of Ti doping on VO 2 .…”

Analysis of titanium and vanadium oxide thin film by method of reactive co-sputtering

“…On the other hand, it should be noted that titanium-vanadium oxides find applications such as electrochromic materials [3] , catalyst, and electrodes for lithium cells [4] or complexometric titration. Interesting researches on composites of vanadium and titanium oxides have been reported [5][6] . For example, a spatially-graded band gap was formed in the Ti 1-x V x O 2 film by distribution in the composition [6] .…”
