Abstract Spatially resolved dynamically reconfigurable control of thermal emission has comprehensive implications for fundamental science and technological applications, such as camouflage adaptive radiative heating/cooling. Materials systems that can spatially with dynamic reconfigurability, simple manufacturability, a large range have not been explored, so far. Here, platform consisting three components (a material phase transition hysteresis, photonic device field‐optimized planarized...
In the pursuit of energy efficient materials, vanadium dioxide (VO2) based smart coatings have gained much attention in recent years. For window applications, VO2 thin films should be fabricated at low temperature to reduce cost commercial fabrication and solve compatibility problems. Meanwhile, thermochromic performance with high luminous transmittance solar modulation ability, as well effective UV shielding function has become most important developing strategy for ideal windows. this...
A novel thermochromic WO<sub>3</sub>/VO<sub>2</sub>/WO<sub>3</sub> sandwich structure was deliberately designed and deposited by a reactive magnetron sputtering technique.
Poly(tetrafluoroethylene) (Teflon) has been selected as the self-template structural material in preparation of VO2 films using a reactive magnetron sputtering method and post-annealing process. with spontaneous random nanoporous structures growing on quartz glasses have deliberately established via bottom-up processing through this novel facile approach. The exhibit an excellent optical performance based localized surface plasmon resonance, ultrahigh luminous transmittance (Tlum-L) up to...
For VO2-based smart window manufacture, it is a long-standing demand for high-quality thin films deposited at low temperature. Here, the thermochromic of VO2 were by magnetron sputtering method fairly temperature 250 °C without subsequent annealing embedding V2O3 interlayer. acts as seed layer to lower depositing and buffer epitaxial grow film. The VO2/V2O3 display high solar modulating ability narrow hysteresis loop. Our data can serve promising point industrial production with degree crystallinity
The VO2 film with "movable" antireflective (AR) coating was initially designed and successfully prepared to deal the challenges that faced. AR layer, including water other organic solvents, not only endowed active-passive regulation mode but also dramatically enhanced thermochromic performance. Furthermore, we combined solid movable antireflection layer for further structural optimization, result turned out be superior any multilayer structure reported previously. We believe this...
Here, we fabricated an oxygen-deficient WO3-x crystalline/amorphous homojunction with a strong and tunable localized surface plasmon resonance (LSPR) absorption realized selective solar modulation over infrared light by controlling the experimental parameters. The shows good LSPR stability in photochromic cycles, which paves way to control applications.
Pursuing excellent photochromic (PC) properties is still a longstanding challenge for energy-efficient smart coatings. Herein, we have prepared novel series of self-coated crystalline WO3-amorphous WO3−x homojunctions by one-step hydrothermal process, in which oxalic acid was used as capping agent to prevent polycondensation and the crystallization [WO6]. The as-prepared nanopowders with tight interfaces large specific surface area rich electrons, leads dramatic PC property reaching up ΔTsol...
V2O3 was recognized as one of the clearest examples Mott-Hubbard physics but rarely treated transmittance modulating coatings based on metal-insulator transition. Here, we deposited high quality epitaxial thin films sapphire (001) substrates well polycrystalline glass or Si substrates, measured optical properties during cooling and heating, discussed ability using fully reversible hysteresis loops. Meanwhile, also optimized electrical performance V2O3/SiNx/Si samples by W-Ti co-doping. The...
Coating of VO2-based thin film has been extensively studied for fabricating energy-saving smart windows. One the most efficient ways high performance films is to create multi-nanolayered structure. However, it highly challenge make such layers in using conventional methods. In this work, a facile two-step approach established fabricate multilayered VO2-TiO2 films. We first deposited amorphous upon sputtering, and then anneal them transform phase into alternating Ti- V-rich nanostructure via...
Co-doping of multiple ions can effectively adjust the biological properties hydroxyapatite (HA) for various biomedical applications. In this study, we prepared Sr 2+ and Cu double-doped hollow HA characterized them by SEM, EDS, XRD, FTIR, other methods. We found that were uniformly distributed in carbonic acid microspheres. As proportion metal elements increases, microspherical appearance crystallinity also change. addition, porous titanium scaffolds through 3D printing technology...
Vanadium dioxide of B-phase [VO2(B)] has been considered as an ideal cathode material and storage materials, but was rarely treated optical modulating coatings based on the metal–insulator transition.
