single crystals that irradiated with 600 keV
4 MeV and 5 MeV Kr ions were investigated in 320 kV high voltage Experimental Platform (IMP
Lanzhou) by infrared spectra and fluorescence spectroscopes.In the low-energy region
single ion tracks are well separated and the damage process is dominated by the formation of simple color centers such as F
2
centers.For the high energy ions
the energy density in ion tracks produced at high stopping power is larger
and consequently the defect concentration increases significantly.At higher defect densities
the distance between single defects is smaller facilitating aggregation of individual electron centers to defect clusters and also defect annihilation by recombination of hole and electron centers.The latter process determines the limited efficiency of color-center creation under heavy-ion irradiation.Using the unified thermal spike model
it is possible to fully describe the experimental data
which clearly demonstrate a synergy between the nuclear energy loss and the electronic energy loss.
