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.
