Polycrystalline W03 films have been prepared which exhibit high near infrared reflectance (≈69% at 2.5μm wavelength) when lithiated. This is a significant increase in near infrared reflectance over what has been previously reported for lithiated W0₃. The films also exhibit a decrease in the Drude scattering parameter and a reversible structure change to higher symmetry (monoclinic to cubic) with increased lithiation. The results are consistent with models previously reported; and both the possibility of further imprvement and its significance for smart window^TM glass glass will be discussed.
