Abstract: Here, we report on the effect of chemical substitution on the structural and optical properties of Cu-doped CaTiO₃ (CTO) polycrystalline powders synthesized by the polymeric precursor method. Our findings are discussed based on the structural order-disorder effects originating from the modification of the Ca_1−xCu_xTiO₃ microcrystal matrix. These results may elucidate the compositional modulation and methods of controlling the structural design, as well as reveal the changes in the optical behavior of this system at an atomic level.
