Js. Lee et al., EFFECTS OF SEEDING LAYER ON ORIENTATION AND PHASE-FORMATION OF SOL-GEL-DERIVED LANTHANUM-MODIFIED LEAD-ZIRCONATE-TITANATE FILMS ON GLASS, JPN J A P 1, 34(4A), 1995, pp. 1947-1951
Sol-gel-derived lanthanum-modified lead zirconate titanate (PLZT) thin
films with La/Zr/Ti ratios of 9.5/65/35, 15.5/40/60 and 18/30/70 were
prepared on Coming 7059 glass substrates using a seeding layer [PLZT(
14/0/100)]. The X-ray diffraction patterns and the microstructures of
the films were investigated. The PLZT(9.5/65/35) thin films without th
e seeding layer consisted of both pyrochlore and amorphous phases. How
ever the PLZT(9.5/65/35) thin films with the seeding layer showed pref
erred orientation as well as higher perovskite phase content. The orie
ntation of the film varied with the thickness and the heat treatment o
f the seeding layer. The results will be discussed in terms of the eff
ects of the seeding layer on the orientation and the content of the pe
rovskite phase of the PLZT thin films on glass substrates.
