Highly transparent multilayered SnO2–TiO2–WO3 inverse opal nanostructure for enhancing effectivity and stability of near-infrared modulation in advanced electrochromic smart window.

A Systematic Review of the Most Recent Concepts in Smart Windows Technologies with a Focus on Electrochromics

“…They achieved an outstanding result of ∆T NIR = 80%. Another system featuring hybrid multi-layered inverse opal (IO) nanostructure composed of tin (SnO 2 ), titanium (TiO 2 ), and tungsten (WO 3 ) oxides developed by Nguyen et al [73] was reported in 2019 to modulate up to 63.6% NIR radiation at the wavelength of 1200 nm. Inverse opal (IO) nanostructures are three-dimensionally ordered microporous materials formed through the infiltration of an artificial opal with a material precursor.…”

Aqueous synthesis of tin- and indium-doped WO3 films via evaporation-driven deposition and their electrochromic properties

“…[1][2][3][4][5] Tungsten oxide (WO 3 ) is a typically used cathodic electrochromic material because of its relatively fast color change and good stability. [5][6][7][8][9][10][11] Two-terminal electrochromic devices based on cathodic WO 3 electrodes and appropriate anodic materials such as dimethyl ferrocene, 12 hydroquinone, 13 tetrathiafulvalene 14 (soluble anodic species), and NiO, 15,16 polyaniline 17 (insoluble anodic species) have been widely studied for practical applications. The electrochromic reaction of WO 3 can be represented as:…”

“…Moreover, the aqueous route is thought to allow for the doping of WO 3 materials with various metal ions because water can dissolve many different metal salts. Here, we prepared amorphous and crystalline M-doped WO 3 lms (M ¼ Sn or In) by a low-speed dip-coating technique with simple aqueous solutions containing only (NH 4 ) 10…”

Fabrication and Characterization of Transparent and Scratch-Proof Yttrium/Sialon Thin Films

“…Transparent screens and covers are essential components of various technology products such as solar cells, liquid crystals displays, electrochromic windows, and touch screens and many other applications [ 1 , 2 , 3 , 4 ]. These screens and covers are crucial for protecting sensitive components of these devices while still allowing light to pass.…”
