The present work deals with the preparation of pure and Gd doped LAMOX powders and thin films by a Pechini's based solution method. Gd doping proved to be efficient not only in stabilising the β form at room temperature but also in reducing the particle size and improving the film quality. Best results for both particles and films were achieved using 10 mol.-% dopant, which corresponds to the solubility limit. Concerning substrates, it was verified that they play a key role in film microstructure. Homogeneous and crack free films were obtained on glass, silicon and alumina substrates. Film density is quite dependent on the type of substrate, and glass substrates provided the densest films. The average thickness is ~150 nm for one layer film. [ABSTRACT FROM AUTHOR] |
