Refractive index values are reported for sol-gel derived PbTiO3 thin-layers as a function of thermal processing conditions., Dense amorphous layers were formed at 350 degC n 2.35 with crystallization at 450 degC -n 2.65. A spin-casting method is described for the deposition of coatings. Ellipsometry was used to monitor optical properties as a function of heat-treatment conditions.
