Abstract

High frequency EPR spectra of europium(II)-doped BaAl2O4 powder phosphor have been analysed. Spectral simulation was carried out by a Fourier transform Monte Carlo method using an equation derived from the second-order perturbation of the energy levels for S=7/2. It is found that the spectra can best be interpreted in terms of europium(II) ions in two different sites. One quarter of the europium(II) ions are located in a site with a ∣D∣ of 0.345 cm-1, and the remaining europium(II) ions are in a site with a ∣D∣ of 1.08 cm-1. Estimated values of ∣E∣ are equal to 1/3
