In the paper, the changes of structures and optical properties of metal ions doped modified CaTiO3 prepared under different magnetic field intensities (up to 12 T) and 800 ℃ are studied. The results indicate that the photo absorption performances are enhanced with the ions doped concentration increasing and red shift occurs significantly. With the same doped concentration, the photo absorption performances of the samples prepared under magnetic field are improved compared with under no magnetic field, while there are little differences among the absorption curves of these samples prepared under different magnetic field intensities. Furthermore, it is observed that the X-ray diffraction curve peaks of pure CaTiO3 prepared under magnetic field are all left-shifted and cutoff wavelengths of UV-vis are augmented, which indicates that the interplanar spacing and lattice constant are increased while the band gap is narrowed.
