Abstract
Amorphous Bi2O3-TiO2 and Nb2O5-TiO2 transparent films were successfully prepared by dip coating method, using Bi-Ti complex alkoxide and corresponding metal alkoxide solutions, respectively. The films were amorphous up to 300 or 500°C and highly transparent from 500 to 2000nm. The χ(3) values obtained were mostly in the order of 10-12 esu although the films had high porosity, and the values of 10-11 esu were expected for fully dense amorphous films.
