N2 - The preparation of a co-doped BaTiO3:Er, Yb compound was investigated using alkoxide precursors. The complex alkoxide was hydrolyzed under specific conditions using chelating agents [(AcAc)H and H-(OAc)], and nano-size powders and films of perovskite compounds were obtained. The nanostructure materials were formed through nucleation-aggregation growth. Through a comparison of co-doped BaTiO3:Er, Yb compounds (with and without chelating agents), important differences in shape and size of the particles were found. In addition, the use of chelating agents during the sol-gel process allowed us to obtain optical BaTiO3:Er, Yb thin films. The results suggest that the particle size and shape can be tailored in the current system by manipulating the simultaneous use of chelating agents and the crystallization temperature. Consequently, a wide range of particle size has an effect on the crystal structures.
