【 摘 要 】

Temperature-dependent Eu3+luminescence spectra in GaN(Mg):Eu can be assigned to, at least, two distinct Eu3+centres, denoted by Eu0 and Eu1. The splitting energy levels of the7FJ(J=1,2) multiplets for the Eu0 and Eu1 centres have been calculated using the equivalent operator Hamiltonian for C3vcrystal field with the addition of an odd parity distortion.
