1. Optical properties and solar selectivity of inhomogeneous metal-insulator coatings
Sammanfattning : .... LÄS MER
2. Thermochromic VO2-based materials for smart windows : Progress towards applications in buildings
Sammanfattning : Vanadium dioxide is a well-known thermochromic material, whose optical properties can be varied reversibly in response to fluctuation of temperature. It is attractive in various fields due to its unique properties as well as its prospective applications. LÄS MER
3. Optical Absorption and Electrical Conductivity in Lithium Intercalated Amorphous Tungsten Oxide Films
Sammanfattning : Optical and electrical properties of electrochemically lithium ion intercalated thin films of x-ray amorphous tungsten oxide made by magnetron sputtering on glass substrates coated with a thin layer of conductive tin doped indium oxide, have been studied. The composition and the density of the films were characterized by the ion beam analysis methods Rutherford Backscattering Spectroscopy and Elastic Recoil Detection Analysis. LÄS MER
4. Electrochromic Properties of Iridium Oxide Based Thin Films
Sammanfattning : Electrochromic iridium oxide (IrOx) and iridium-tantalum oxide (IrTaOx) thin films were prepared by reactive magnetron sputtering. Composition, density, and structure were determined using Rutherford backscattering spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and electron energy loss spectroscopy.

5. Functionalization of polymer electrolytes for electrochromic windows
Sammanfattning : Saving energy in buildings is of great importance because about 30 to 40 % of the energy in the world is used in buildings. An electrochromic window (ECW), which makes it possible to regulate the inflow of visible light and solar energy into buildings, is a promising technology providing a reduction in energy consumption in buildings along with indoor comfort.
