“…Considering the photochromic mechanism of TMOs, one notes that this effect is mainly contributed by photo-induced reduction of TMOs or trapping of photo-generated electrons, and occasionally by oxygen vacancies. These studies underscore the opportunity of TMOs in photonic applications and may be useful for design of new inorganic photochromic materials, such as the composite and hybrid systems [79,123,167,171,[206][207][208][209][210].…”

Transition-metal oxides -including tungsten oxide, molybdenum oxide, titanium dioxide, vanadium pentoxide, niobium pentoxide and zinc oxide -exhibit photochromism upon bandgap excitation. These oxides constitute an important group of inorganic chromogenic materials, which is of great significance in the perspective of science and technology. During the past several decades, great progresses have been made in the microstructure, photochromic behavior and mechanism of these oxides, specifically of tungsten oxide. These studies underscore the opportunity of using these materials in photonic applications. The details will be presented in this review.

“…8,23 However, hybrid structures greatly challenge the composition design and increase the complexity of WO 3 based photochromic systems while the intrinsic WO 3 photochromism has been rarely reported. 5,[22][23][24][25] Herein, we report the hydrothermally prepared hydrated tungsten oxide nanosheets exhibiting fast and reversible intrinsic photochromic response. During the hydrothermal process, the amphiphilic triblock copolymer PEO-PPO-PEO (Pluronic P123) can work as the directing agent, which can help to induce the formation of a layered nanostructure.…”

“…14 Furthermore, we also in situ synthesized POM nanoparticles in polyelectrolyte multilayers by means of this method. 15 Recently, Chen et al 16 reported the fabrication of photochromic multilayer films based on metal oxides and organic molecules. As we know, polymers are quite versatile for producing self-assembly thin films due to their varied structural properties and functionalities.…”
