dc.description.abstractFor this research, we studied the influence of titanium tetrachloride (TC) and titanium tetraisopropoxide (TTP) precursors on CaTiO3 (CTO) synthesis by employing a microwave-assisted hydrothermal (MAH) method regarding their respective short-, medium- and long-range features to determine if the use of different titanium precursors enhances the structural evolution of the material. The growth mechanism for the formation of the micro-cube-shaped CTO is proposed to obtain nanoparticle aggregation of self-assembly nanoplates. The disorder coupled to the oxygen vacancies of [TiO5]-[TiO6] in complex clusters in the CTO 1 powder and twists in bonding between the [TiO6]-[TiO6] complex clusters in the CTO 2 powder were mainly responsible for photoluminescent (PL) emission.
