• (WO 3 ) 100-X C X thin films (x=0-9.3 at%) were cosputtered on indium-tin-oxide glass substrate with W and C targets by reactive dc magnetron sputtering at room temperature. The effects of doped C on the microstructure and optical properties of the (WO 3 ) 100-X C X thin film were examined by field emission scanning electron microscopy with energy dispersive X-ray spectroscopy, X-ray diffraction, and a spectrophotometer. It was found that all of the as-deposited films were amorphous. The average transmittances of bleaching and colored WO 3 film in the 400-700 nm range were 75% and 65.9%, respectively. The variation in average transmittance of the bleaching and colored states of (WO 3 ) 90.7 C 9.3 film was 68.3%. The average transmittance of bleaching (WO 3 ) 100-X C X thin films did not vary with C doping. However, the average transmittance of colored (WO 3 ) 100-X C X film decreased to <;48% after C doping. In addition, the optical transmittance contrast of (WO 3 ) 100-X C X thin films was found to be suitable for blue laser wavelength recording.
