Abstract

It is shown that practical spectrally-selective transmittance modulation can be achieved with thin (50-100nm) WO3 films, and therefore such films should be useful for fabricating electrochromic windows. The transmittance and reflectance modulation results are compared with theoretical predictions. The results indicate an excess intraband absorptance, which is attributed to free electron scattering arising from extended defects.
