Optical bandgap plots
WebApr 13, 2024 · The bandgap values obtained from the Tauc’s plot were given in Table 2. The bandgap of the samples decreased with doping. Because Ce and Ti have different ionic radii, adding cerium atoms to strontium titanite has created some imperfections in the material. These lattice distortions lead to the lowering of the bandgap of the material.
