PLZT thin film is an attractive materials due to its large electro-optic and nonlinear optical effect. PbTiO3 and PLZT (10/0/100, 28/0/100) thin films on different substrates have been prepared by sol-gel process. (100) oriented PbTiO3 film on SrTiO3 (100) single crystal substrate and (111) oriented PLT films on sapphire (0001) substrate have been obtained. Transmission of the films is more than 80% in visible wavelength range. Some electric and nonlinear optical properties have been studied.
