| 英文摘要 | SrLaAlO4 materials irradiated with 350 MeV Fe-56(21+) ions have been studied by Raman spectroscopy, Potoluminescence (PL) spectra and X-ray diffraction (XRD). A wide luminous band appeared after Fe-56(21+) irons irradiation; and it increase with irradiation dose. The PL peaks intensity of SrLaAlO4 crystal increased rapidly; and the peaks intensity reached the maximum threshold dose at 5 x 10(10) ions/cm(2). A series of relatively sharp emission peaks are caused by the transition from E-2(g) to (4)A(2g) at the spectrum of 1.82eV-2.14eV. In the oxide fluorescent material, the high level excitation transitions ( (4)A(2g ->) T-2(2g)) are parity and spin forbidden. The peaks caused by the (4)A(2g) -> T-2(2g) transitions is not clearly observed in many fluoride phosphors; while, after high-energy (56)Fe(21+ )ion irradiation, the parity and spin-forbidden transitions have been observed at 2.25eV-2.48eV. It was found that the spin forbidden transition was allowed to somewhat extent due to the lattice vibration; and, the spin orbital coupling caused by mixing (4)A(2), E-2, T-2(2) and T-4(2) states. |
