Effect of reagents mixing on the thermal behavior of sol-gel precursors for silica-based nanocomposite thin films



The paper presents, based on TG-DTG-DSC data, some results of the thermal decomposition of some complex sol-gel precursors used for the deposition of mesoporous ZnO/SiO2 nanocomposite thin films for gas sensing applications. The effect chemical composition of the sol and reagents mixing during the sol preparation is discussed. The chemical nature of ZnO source (zinc acetate solid salt, zinc acetate alcoholic solution or ZnO nanopowder) used for the sol preparation significantly affects the thermal decomposition of complex precursor and the microstructure and properties of the nanocomposite thin films.
