Abstract
Lithium aluminate (LiAlO2) is the candidate material for solid tritium breeder applied in the developing fusion reactors. The research of its defect behavior under ion irradiation was proceeded in the negative ions induced luminescence setup of the GIC4117 Tandem accelerator in Beijing Normal University. The ion beam induced luminescence (IBIL) measurement was performed by 20Â keV Hâ ions at room temperature. The luminescence spectra showed seven emission bands: the 4.55Â eV may due to a self-trapped exciton (STE), the 4.06Â eV and the 1.72Â eV may due to impurity or intrinsic defect, the 3.54Â eV due to F center, the 3.20Â eV due to F+ center, the 2.93Â eV due to F2 center, the 2.30Â eV due to F-center aggregates (Fn center), respectively. The intensity evolutions of each band with fluence were presented and the corresponding mechanisms were discussed.
