摘要：
The First-principles based on plane-wave pseudo-potentials methods was applied to investigate the lattice parameter, electronic structure and optical property of Al2O3 (0001) by Ti Ion implantation. The calculation result show that the color center is form by transfer electron between 3d of Ti ion orbit energy level and Al ion 3p orbit energy level, and the absorption peak is located at the region of 2.1eV, which located in 400nm-450nm, where corresponding to the color and the color was caused by F color center.
