“…As can be seen, at 450 nm the refractive index is 1.83 and remains over 1.78 to wavelength of 1650 nm. When these values are compared to pulsed laser deposited 14 and sputtered 13 PLZT thin films, the index in sol-gel prepared film is remarkable smaller. This kind of behavior is typical for…”

In this study, the sol-gel process to fabricate directly UV-photopatternable lanthanum-doped lead zirconate titanate (PLZT) films was investigated. Photosensitive films were obtained via chemical methacrylic acid modification of metal organic PLZT precursors. Spin-on deposited films were patterned using direct UV-photolithography process. Patterned films were annealed in air, in order to obtain perovskite type crystalline material. AFM and XRD techniques were used for the characterization of the material and fabricated structures. The sol-gel processed PLZT films had good crystallinity, they were crack-free, and had low surface roughness. The films exhibit electro-optic effect being therefore interesting to be used in active integrated optic devices.

“…The use of thin films in electro-optic device can lead to a reduction in device size and an increase in interaction efficiency. A large number of ferroelectric thin films have already been investigated as candidates for electro-optic applications, including PZT [4], PLZT [5], and SBN [6]. Ba 1−x Sr x TiO 3 (BST) is an excellent material because of its unique combination of large dielectric constant, large electro-optic coefficient, and low optical losses.…”

Ba 0.65 Sr 0.35 TiO 3 (BST) thin films have been prepared by radio frequency magnetron sputtering on fused quartz at different substrate temperatures. Optical constants (refractive index n, extinction coefficient k) were determined from the optical transmittance spectra using the envelope method. The dispersion relationship of the refractive index vs. substrate temperature was also investigated. The refractive index of BST thin films increased from 1.778 to 1.961 (at l=650 nm) as deposited temperature increases from 560°C to 650°C. The extinction coefficient of asdeposited BST thin films increased with the increase of the oxygen-to-argon ratio, which was due to the change of the film stoichiometry, structure, and texture of BST thin films. The oxygen-to-argon ratio also affected the fluorescence spectra. The fluorescence peaks intensity was greatly increased, apparent frequency shift was detected, and the linewidth became narrow as the ratio of oxygen to argon increased from 1:4 to 1:1. The fluorescence spectra also indicated the band transition of BST thin films was an indirect gap transition.
