Abstract

Ultraviolet-visible spectrophotometer was used to study optical properties of Ba_xSr_1-xTiO₃ (BST) system ferroelectric thin films derived by sol-gel process. Transmission spectrum show that the thickness, refractive index and the optical band gap of films on fused silica are changed with annealing conditions due to the densification with pore collapse and the phase transformation. The refractive index n of BaTiO₃, Ba_0.7Sr_0.3TiO₃, SrTiO₃, and Ba_0.7Sr_0.3TiO₃+1at%Mn thin films annealed at 800 degree(s)C are about 1.987, 1.902, 1.8 and 2.044 at 450 nm, 550 nm, 650 nm, and 550 nm, respectively. The bandgap of well-crystallized BST thin films is about 3.63 eV.
