Advanced developments in nonstoichiometric tungsten oxides for electrochromic applications

“…[52][53][54] Poly (3-hexylthiophene) (P3HT) is a regioregular semiconducting polymer that shows EC modulation under a small electrical bias polarities and acts as an anodically coloring material. 55 As well-known WO 3 is a cathodically coloring material, therefore a hybrid composed of P3HT and WO 3 as two active electrochromics demonstrated a dual bend EC performance. 55 In the dual EC device, P3HT…”

“…has been used as the anode coloring material and WO 3 as cathode coloring material, therefore, the charges transfer from WO 3 towards P3HT makes it the color, meanwhile the colors of both the materials bleached in the opposite direction. 55 To achieve multiple colors and enhance the functionality of all-in-one type EC devices the incorporation of several EC chromophores is inevitable. 56 They can achieve the simplest device configuration because of the facile fabrication using versatile solution processes (e.g., spin coating and printing) and easily tunable device characteristics such as transmittance contrast, color, operating voltage, and cyclic stability by varying the concentration of chromophores 57,58 and tuning the electrochemical properties 59 or molecular structures 60,61 of redox species.…”

Influence of Crystalline and Shape Anisotropy on Electrochromic Modulation in Doped Semiconductor Nanocrystals

“…26,37 Visible transparency with selective near-infrared modulation is of interest for controlling thermal gain while maintaining daylighting. [43][44][45] In our study, significant modulation of transmission over a broad range of near-infrared wavelengths is achieved while maintaining high visible transparency. Figure S7 shows the modulation achieved by thin (thickness ≈ 130 nm) electrochromic films of nanorods and nanoplatelets in Na + electrolyte.…”

Prussian blue‐based inorganic flexible electrochromism glucose sensor

“…Electrochromic devices are known for reversibly changing their optical properties (reflectance/transmission/absorbance) under external applied bias and the materials exhibiting such properties are termed as electrochromic materials [10][11][12][13]. In addition to the multifunctional property, flexible electrochromic devices have an additional feature of deformation making them potentially useful in curved windows, military camouflage, etc [14][15][16].…”
