Properties of zinc titanates synthesized by microwave assisted hydrothermal method.

摘要: Zinc titanates are compounds that have shown great application versatility, including in the field of semiconductors. Solid state reactions, polymeric precursor method and hydrothermal most mentioned synthesis these literature. In present work, we use microwave assisted (MAH) to synthesize zinc titanate evaluate its potential for solar cell applications through structural optical characterization techniques. The synthesized samples were also subjected a variable temperature heat treatment range 500 °C-800 °C. analysis showed crystallization material starts at °C submitted temperatures 600 formation two phases titanates, being cubic phase ZnTiO3, considered rare literature, predominant up 800 characterization, based on techniques photoluminescence spectroscopy UV-Visible spectroscopy, photoluminescent activity energy band gap increased with increase treatment, having highest response 700 °C, facts can be linked ZnTiO3 simultaneous rhombohedral Finally, highlight as important results, fact it was possible obtain lower than reported heat-treated sample is one lowest expenditure greatest dye-sensitized cells (DSSC's).
