Thermally-induced microstructural evolution in nanoparticle-based CuO, WO and CuO-WO thin films for hydrogen gas sensing
Kalyani Shaji, Stanislav Haviar, Petr Zeman +4
This study systematically investigates the microstructural evolution of nanoparticle-based CuO, WO, and composite 'CuO-WO' thin films induced by their post-deposition annea…
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…
Extraordinary oxidation behavior of W-Zr thin-film metallic glasses: A route for tailoring functional properties of W-Zr-O films
Petr Zeman, Michaela Äervená, JiÅà HouÅ¡ka +3
The oxidation behavior of W-Zr thin-film metallic glasses (TFMGs) with 32, 48 and 61 at.% Zr, prepared by dc magnetron co-sputtering, was comprehensively studied after annealing in…
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…
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…
