الملخص الانجليزي
Five samples of barium titanate which doped with Mg and Mn (Ba(1-x) Mg x Ti(1-x)MnxO3) (where x = 0.01, 0.2, 0.03, 0.04,
and 0.05). The samples were synthesized using solid state reaction method, at 1200◦C. All samples were investigated by
Ultraviolet Visible Spectroscopy. The results of UV technique proved that the absorption and the optical band gap
energy of five samples have been increased with increasing of Mg and Mn doping at (3.18, 4.31, 4.35, 4.39, and 4.43
eV). On the other hand, the refractive indexes of the prepared samples have been decreased with dopant (2.31, 2.10,
2.09,2,089, and 2.083) respectively
