The Bi1 Eu,Fe03 (BEFO,, x = 0, 0.03, 0.05, 0.07, 0.1) films were grown on LaNiO3 coating Si substrates by pulsed laser deposition. X-ray diffraction patterns indicate that the films exhibit a (1 0 0)-highly oriented pseudocubic perovskite crystal structure. Scanning electron microscopy exhibits that the number of island-like structures decreases with increasing Eu dopant. The position of the A1-1 mode of the films in the Raman spectra shifts to higher wavenumber with increasing x. With increasing the amount of Eu, the refractive index increases and the extinction coefficient decreases. In addition, the band gap of BEFOx films decreases with increasing Eu dopant. 2014 Elsevier B.V. All rights reserved.
