| Abstract: | On the extended-ion method has been used to investigate luminescence energies of the Self-Trapped Exaction(STE) and absorption energies of theVk-center in Ammonium Halide Crystals.Theenergy and the corresponding equilibrium configuration of crystal are determined by minimizing the totalenergy of the system.A hybrid pseudo potential method is used to determine the energy and states of thedefect electron.The results showthatthe luminescence energies of the STE and the absorption energies oftheVk-center are in good agreement with the experimental results. |
