“…[9] Nanomaterials of undoped vanadia employed in electrochromic studies include nanowires, [14][15][16] inverse opals (IOs), [8] and mesoporous films. [17] Although these recent attempts brought about an improvement in electrochromic performance, the reported switching times remained 1-2 orders of magnitude above the desired video rate of 24 frames per second.…”

“…[17] Although these recent attempts brought about an improvement in electrochromic performance, the reported switching times remained 1-2 orders of magnitude above the desired video rate of 24 frames per second. [8,[14][15][16][17] This is mainly due to the use of sub-optimal V 2 O 5 morphologies in terms of their structural dimension, connectivity, and integrity. Conceptually, an ideal chromogenic material should be a mesoporous fully interconnected network consisting of struts with a homogeneous diameter and a narrow pore diameter distribution, enabling effective electrolyte infiltration and good charge transport.…”

Enhanced Electrochromism in Gyroid‐Structured Vanadium Pentoxide

et al. 2012

Manufacturing V(2)O(5) in a 3D periodic highly interconnected gyroid structure on the 10 nm length scale is shown to lead to a significant electrochromic performance enhancement. The structured devices surpass previous inorganic electrochromic materials in all relevant parameters: the switching speed, coloration contrast, and composite coloration efficiency. In particular, the 85 ms switching speed lies within a factor of two of video rate. Enhanced ion intercalation into the gyroid morphology can be extended to other transition-metal oxides and is therefore promising for lithium ion batteries, supercapacitors, and sensors.

Recent developments in the synthesis of transition metal oxides in the form of thin films have opened up opportunities in the construction of electrochromic devices with enhanced properties. Transition metal oxides like WO3 and MoO3 have good electrochromic properties and these oxides can also change their optical properties when a voltage pulse is applied. These electrochromic materials are used for displays, gas sensors, rear-view mirrors and smart windows for energy saving applications. There are numbers of different techniques used for the deposition of stable thin films of these oxide materials. Tungsten Oxide (WO3) is the best suited material for energy conservation applications. Thin films of WO3 are deposited by various techniques that offers flexibility, allows the fabrication of required topographical, physical, crystallographic, desired geometrical and metallurgical structures. This review paper is aimed to summarize applications of WO3 thin films as an electrochromic material and the effect of various deposition techniques on its electrochromic and optical properties.

“…Several researchers have attempted to employ the concept of nanotechnology to improve the drawbacks of thin-film-based electrochromic devices (ECDs) such as contrast, cycling life stability, and slow switching time between the colored and bleached states. The researcher developed transition metal oxide nanowires based ECDs that show a great improvement in coloration efficiency, contrast, and durability [5,6]. These ECDs show promising switching rate, life stability, and contrast.…”

Nanoparticle TiO 2 doped WO 3 thin films by pulsed spray pyrolysis technique have been studied on fluorine tin doped (FTO) and glass substrate. XRD shows amorphous nature for undoped and anatase phase of TiO 2 having (101) plane for nanoparticle TiO 2 doped WO 3 thin film. SEM shows microfibrous reticulated porous network for WO 3 with 600 nm fiber diameter and nanocrystalline having size 40 nm for TiO 2 nanoparticle doped WO 3 thin film. TiO 2 nanoparticle doped WO 3 thin film shows ∼95% reversibility due to may be attributed to nanocrystalline nature of the film, which helpful for charge insertion and deinsertion process. The diffusion coefficient for TiO 2 nanoparticle doped WO 3 film is less than undoped WO 3 .
