Abstract

A series of sol-gel derived, La-doped PbTiO₃ films, with compositions Pb_1-x/100 La_x/100 T_1-x/400O₃ (PLT X) with La content, x = 0, 5, 10, 15, 20, 25, 28, 30 and 32 were prepared on Coming 7059 substrates. These films were fired at 400-600C for 30 mins. The phase assembly and phase development were dependent on the precursor chemistries (La content) and processing (firing temperature). The grain size of the crystallized PLT films decreased with higher La content, and PLT films with higher La contents appeared denser. The optical properties of the films were investigated using UV-VIS transmission spectroscopy. Depending on composition and processing conditions, PZT films (2500A thick) with refractive indices of 2.00-2.56, sufficient for waveguiding on Coming 7059 glasses with refractive index of 1.53, and band gaps of 3.11-3.55 eV can be obtained. Exhibiting high refractive indices, these amorphous and crystalline PLT films can be utilized for both passive and active optical applications.
