Abstract
Dielectric lead lanthanum zirconate titanate thin films have been grow n on Si(111) substrates by sol-gel processing. The composition of the films is stoichiometric 9/65/35. When annealed at 450 degrees C, the f ilms were found to be amorphous. The refractive index and the extincti on coefficient of the films were measured in the spectral range of 1.8 -5.5 eV for the first time by photometric spectroellipsometry. The abs orption edge is determined at about 3.7 eV. (C) 1998 Elsevier Science S.A.
