Sputter deposition of Ag-induced WO3 nanoisland films with enhanced electrochromic properties

Bistable Silver Electrodeposition‐Based Electrochromic Device with Reversible Three‐State Optical Transformation By Using WO3 Nanoislands Modified ITO Electrode

“…Preparation of WNs-Modified ITO Electrodes: The WNs-modified ITO electrodes can be fabricated by a previously reported procedure. [24] Before preparing WNs-modified surface, the ITO glass electrodes were ultrasonically cleaned in acetone, alcohol, and deionized water for several minutes sequentially and dried with high-purity nitrogen gas. In order to form hydroxyl groups on its surface, ITO glasses were treated with oxygen plasma for 5 min with a power of 6.8 W (PDC-MG, MING HENG Co. Ltd.).…”

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] Up to now, inorganic EC materials mainly fall into two categories: the first involves the insertion of ions (H + , Li + ) into hosts such as WO 3 , NiO, MoO 3 , TiO 2 , and other transition metal oxides. [2,6,7,[19][20][21][22][23][24][25][26][27][28][29][30][31] It is characterized by reversible and persistent changes in optical in the electrolyte was found to make Ag metal dissolve accelerative. The removal of the Cu ions from the electrolyte can thus obtain good bistability but make erasing operation of the device difficult.…”

“…[ 1–18 ] Up to now, inorganic EC materials mainly fall into two categories: the first involves the insertion of ions (H + , Li + ) into hosts such as WO 3 , NiO, MoO 3 , TiO 2 , and other transition metal oxides. [ 2,6,7,19–31 ] It is characterized by reversible and persistent changes in optical properties when the ions are interspersed. However, most EC devices based on these nonmetal materials can only obtain the transformation between two colors and cannot achieve the reflective mirror optical state.…”

“…The sputtering growth of WO 3 nanoislands on different electrode surfaces is a technology developed by ourselves. [ 24 ] The particle size and distribution density are controllable. Thus, it is very suitable to be used as the rough particle‐modified electrode layer and easy to extend the new effects such as showing multicolor states.…”

Review on recent progress in WO3-based electrochromic films: preparation methods and performance enhancement strategies

“…Apart from pure WO 3 nanomaterials, A-hybrid (A usually refers to the metals, semiconductors, or other conductive materials) WO 3 -based films often exhibit desirable electrochromic properties. 35,36,49,50,126,[148][149][150][151][152][153][154][155][156][157] Nguyen et al 49 prepared WO 3 /Ti 3 C 2 T x hybrid film by the spraycoating method (Fig. 9a) and then assembled a flexible EC device based on the hybrid film and ITO/PET film substrate (Fig.…”
