Abstract

Perovskite-structured Ba_1-xLa_xSnO₃ (x=0.04, 0.06, 0.08) (BLSO) films were epitaxially grown on SrTiO₃ (001) substrates by a sol-gel method. The microstructure and surface of the films were analyzed by X-ray diffraction and atomic force microscopy, respectively. The results show that the films exhibit preferred orientation along the c-axis without cracks or voids. Optical properties were studied in a wide photon energy range between 1.1 and 5.9 eV by spectroscopic ellipsometry. It was found that the optical band gap of the BLSO films increases gradually from 3.42 to 3.73 eV with increasing La concentration.
