摘要：

The self-trapped excitons (STEs) and F centres in MgF2 are studied within the extended-ion approximation. It is found that the STE is in bet a nearest-neighbour F-H pair with C-1 symmetry. The theoretical results for the spectra of the STEs and F centres are in good agreement with experiments. The stable F-H pairs converted from STEs are generated only at the hole excited state of the STEs according to the calculations of the adiabatical potential energy curve of the STE/FH pair. A model of the excited-hole hopping diffusion is proposed to explain the reorientation of the H centre and the formation of the F-H pair under cascade excitation.
