The main objective of this work is the preparation of Eu-doped BaTiO3 in order to analyze both electrical and optical properties. To this end, the objectives shall be the following:
- Synthesis of samples based on Ba1-3xEu2xTiO3 (x=0, x=0.015 and x=0.025) by sol-gel method.
- Structural and micro-structural characterization of the synthesized materials by X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM).
- Electrical characterization of synthesized materials by Impedance Spectroscopy (IS) to study the electrical behaviour of the lanthanide doped samples. Permittivity measurements were also conducted to obtain the transition temperature of the tetragonal to cubic structure, the quality and homogeneity of the samples and the maximum value of permittivity at Curie temperature.
- Optical characterization of synthesized materials by Luminiscence to study in detail the processes of emission 5D0 → 7F0-4 of Eu3+ ion and to study its location in the host lattice. [-]
