Abstract
Nano-crystalline Pb0.72La0.28TiO3 (PLT28) thin films were prepared on glass substrate by RF magnetron sputtering using the sequence of post- deposition annealing process. 150 to 200nm thick films were found to b e comprised of 5nm grains in the perovskite structure. The effective b irefringence shift in the nano-PLT films as a function of applied elec tric field exhibits a quadratic electro-optical behavior. The hysteres is measurement indicated that the films display slim-loop character. E xperimental results showed that the nano PLT film is an electric field -induced ferroelectric.
