“…At present, nanostructured WO 3 are deposited on various substrates to fabricate optical and electrical devices, such as TiO 2 [ 15 ], NiO [ 16 ], ZnO nanowires (NWs) [ 17 ], diamond [ 14 ], Fe 2 WO 6 [ 8 ], and BiVO 4 [ 18 ]. In the last few years, several review reports have been published based on photo catalysts [ 19 , 20 ], electrochromic devices [ 21 , 22 ], gas sensors [ 23 , 24 ], and oxygen-deficient WO 3 [ 25 ]. However, so far there is no review focusing specifically on nanostructured WO 3 optical and electrical devices.…”

Tungsten oxide (WO3) is a wide band gap semiconductor with unintentionally n−doping performance, excellent conductivity, and high electron hall mobility, which is considered as a candidate material for application in optoelectronics. Several reviews on WO3 and its derivatives for various applications dealing with electrochemical, photoelectrochemical, hybrid photocatalysts, electrochemical energy storage, and gas sensors have appeared recently. Moreover, the nanostructured transition metal oxides have attracted considerable attention in the past decade because of their unique chemical, photochromic, and physical properties leading to numerous other potential applications. Owing to their distinctive photoluminescence (PL), electrochromic and electrical properties, WO3 nanostructure−based optical and electronic devices application have attracted a wide range of research interests. This review mainly focuses on the up−to−date progress in different advanced strategies from fundamental analysis to improve WO3 optoelectric, electrochromic, and photochromic properties in the development of tungsten oxide−based advanced devices for optical and electronic applications including photodetectors, light−emitting diodes (LED), PL properties, electrical properties, and optical information storage. This review on the prior findings of WO3−related optical and electrical devices, as well as concluding remarks and forecasts will help researchers to advance the field of optoelectric applications of nanostructured transition metal oxides.

“…Electrochromic materials possess the ability to adjust optical properties such as color, transmittance, and reflectance based on an applied electric field. Tungsten oxide (WO3), as a representative material in this category, demonstrates excellent stability and adjustability in optics [1][2] . However, it suffers from drawbacks such as poor color selectivity, slow response speed, and low efficiency.…”

Different niobium (Nb)-doped tungsten oxide (WO3) nanowire films were prepared by magnetron sputtering and hydrothermal methods, and their performances were analyzed. The experimental results revealed that Nb doping caused the tungsten oxide nanowire structure to become loose, increased the interplanar spacing, and raised the oxygen vacancy concentration, significantly improving the electrochromic properties. However, with increasing Nb doping levels, the cyclic stability of the samples decreased, possibly due to lattice distortion induced by Nb. The analysis demonstrated that the sample doped with 0.5% Nb exhibited optimal electrochromic performance and displayed a 5.68% coloring transmittance and an 83.3% optical modulation range at a wavelength of 633 nm. This study elucidated the influence of Nb doping on the electrochromic properties of WO3 nanowire films.

“…The typical electrochromic cathode material WO 3 was widely studied due to low materials cost, high coloration efficiency, and good chemical stability. , Due to its inferior switching speed and unsatisfactory reversibility, traditional WO 3 materials are unsuitable for some applications . Studies show that the electrochromic performances of WO 3 can be enhanced by combining them with highly conductive metals. − The color-changing performance of WO 3 combined with the highly conductive Cu has been widely recognized.…”

The application of electrochromic devices (ECDs) in smart windows provides a solution for energy savings and environmental protection. Here, a WO 3 nanowire/Cu composite electrode was synthesized as an electrochromic cathode via hydrothermal and electrodeposition. Meanwhile, a TiO 2 nanorod/ NiO composite electrode was also prepared as an electrochromic anode via hydrothermal and electrodeposition. The Schottky junction structure formed between the Cu and WO 3 film interface increases the rate of Li + injection and extraction. In addition, the TiO 2 /NiO heterostructure can enhance the separation of the electrons and protons. The designed ECD exhibited properties of large optical modulation (74.5% at 633 nm), high coloration efficiency (94.1 cm 2 C −1 ), and fast switching speed (3.1/1.6 s for coloration/bleaching). These characteristics make the WO 3 /Cu-TiO 2 /NiO electrochromic device a very promising smart window candidate for lighting control and energy-saving applications.
