19 p, 4.2 MB Review on sol-gel synthesis of perovskite and oxide nanomaterials / Navas, Daniel (Universidad Tecnológica Metropolitana (Santiago, Xile). Departamento de Química) ; Fuentes, Sandra (Center for the Development of Nanoscience and Nanotechnology (Santiago, Xile)) ; Castro-Alvarez, Alejandro (Universidad de La Frontera. Facultad de Medicina) ; Chávez Ángel, Emigdio (Institut Català de Nanociència i Nanotecnologia)
Sol-Gel is a low cost, well-established and flexible synthetic route to produce a wide range of micro- and nanostructures. Small variations in pH, temperature, precursors, time, pressure, atmosphere, among others, can lead to a wide family of compounds that share the same molecular structures. [...]

16 p, 190.5 KB Synthesis and optical characterization of Er-doped bismuth titanate nanoparticles grown by sol-gel hydrothermal method / Fuentes, Sandra (Centro para el Desarrollo de la Nanociencia y la Nanotecnología (Chile)) ; Muñoz, Pamela (Universidad Católica del Norte) ; Llanos, Jaime (Universidad Católica del Norte) ; Vega, Mauricio (Universidad Católica del Norte) ; Martin, Inocencio R. (Universidad de La Laguna) ; Chávez Ángel, Emigdio (Institut Català de Nanociència i Nanotecnologia)
The Er-doped bismuth titanate (BiTiO, BIT) nanoparticles were synthesized by a combined sol-gel and hydrothermal method under a partial oxygen pressure of 30 bar. The composition and morphology were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Raman scattering. [...]

5 p, 477.5 KB Synthesis and structural characterization of nanocrystalline batio3 at various calcination temperatures / Fuentes, Sandra (Centro para el Desarrollo de la Nanociencia y la Nanotecnología (Chile)) ; Céspedes Mulero, Francisco (Universidad Católica Del Norte) ; Muñoz, Pamela (Universidad Católica Del Norte) ; Chávez Ángel, Emigdio (Institut Català de Nanociència i Nanotecnologia) ; Padilla Campos, Luis (Universidad de Antofagasta. Departamento de Química)
Barium titanate (BaTiO3) powders with particle sizes about 50 nm in diameter were synthesized using a hydrothermal route. The powders were characterized using various experimental techniques such as XRD, TEM and Raman spectroscopy, and they showed a good crystallinity and homogeneity without heat treatments. [...]
