Abstract
V02 thin films have been prepared by the sol-gel dip-coating process followed by vacuum heat treatment. The transmittance(T), reflectivity(R) and thickness(d) of these films were measured at room temperature(20°C) and 100°C respectively, and the absorption coefficient( d),refractive index(n) and extinction coefficient(k) were calculated based on the experimen_ tal results. These films show reversible IR transmittance(reflectivity)-Temperature hystere- sis round 67°C, indicating the occurence of phase transition in the films. The IR absorption spectra of the films during heating and cooling were also measured and compared. The possi- bility of using these films for optical storage is discussed.
