Electrochromic materials exhibit variable and reversible optical properties under the action
of voltage pulses. The interest in these materials has increased in the last few years due to
their potential application in a wide variety of optical modulation devices. Tungsten oxide
(WO3) is typical in such devices. In this work, we present a study of the structural and optical
properties of tungsten oxide films deposited on glass and indium tin oxide. The films were
produced by reactive dc magnetron sputtering at different temperatures (room temperature …
