Abstract
Structural and optical properties of e-beam deposited tungsten trioxid e (WO3) films in as-deposited and electrochemically coloured states we re investigated by spectrophotometric and XRD techniques. These invest igations have shown the as-deposited WO3 films to be porous and with s mall amount of HxWO3 pre-existing in them. The films further facilitat e insertion of H+ ions on colouration resulting in tetragonal HxWO3 wi th a = 4.74 Angstrom and c = 3.19 Angstrom.
