High-performance thermochromic multilayer coatings with W-doped VO2 nanoparticles dispersed in SiO2 matrix prepared on glass at a low temperature
Jaroslav Vlcek, Michal Kaufman, Elnaz M. Nia +5
We report a high-performance thermochromic VO2-based coating prepared by using a three-step process, consisting of magnetron sputter depositions of SiO2 films and V-W films and the…
New polymorph γ-CuWO4 inspired by γ-CuMoO4: experimental identification and theoretical verification
Jiri Houska, Stanislav Haviar, Jiri Capek +4
In the context of our efforts to develop hydrogen gas sensors, two samples of ternary CuWO4 with the same crystalline structure have been prepared by two different non-equilibrium…
A low-temperature synthesis of strongly thermochromic W and Sr co-doped VO2 films with a low transition temperature
Michal Kaufman, Jaroslav Vlcek, Jiri Houska +4
The reversible semiconductor-to-metal transition of vanadium dioxide (VO2) makes VO2-based coatings a promising candidate for thermochromic smart windows, reducing the energy consu…
Role of Zr in Cu-rich single-phase and nanocomposite Cu-Zr: molecular dynamics and experimental study
Jiri Houska, Mariia Zhadko, Radomir Cerstvy +2
The non-equilibrium atom-by-atom growth of Cu-rich Cu-Zr thin films has been investigated by a combination of magnetron sputter deposition and molecular dynamics simulations. We fo…
Design and Scalable Synthesis of Thermochromic VO2-Based Coatings for Energy-Saving Smart Windows with Exceptional Optical Performance
Michal Kaufman, Jaroslav Vlcek, Jiri Houska +2
We report strongly thermochromic YSZ/V0.855W0.018Sr0.127O2/SiO2 coatings, where YSZ is Y stabilized ZrO2, prepared using a scalable deposition technique on standard glass at a low…
