摘要：

Uniform and transparent PbZr0.40Ti0.60O3 ( PZT) amorphous thin films were deposited on the fused silica substrates using a modified sol-gel processing. The optical properties of PZT amorphous thin films were investigated in the wavelength range of 200 similar to 1100nm. The refractive index, the extinction coefficient and the film thickness were calculated by a classical envelope method. The dispersion of the refractive index is well explained by the single-term Sellmeier relation. The band gap of the PbZr0.40Ti0.60O3 thin films is about 3. 78eV using Tauc's theory.
