Modification in the microstructural and electrochromic properties of spray-pyrolysed WO3 thin films upon Mo doping
TL;DR: In this paper, the 5 at% Mo-doped tin oxide-coated glass substrates were grown onto the glass and fluorine-dopined tin oxide coated glass substrate using chemical spray pyrolysis technique and X-ray diffraction analyses revealed that all the films possess orthorhombic phase of WO3.

Optical and photoelectric properties and colour centres in thin films of tungsten oxide
TL;DR: In this paper, the optical absorption spectra of amorphous and crystalline thin Wo3 films have been measured in the temperature range 110° to 500°K and the temperature coefficient of the band edges was found to be − 5.0 × 10−4 eV/°K.
