  • The high frequency EPR spectra of SrAl2O4 doped with gadolinium(III) as a probe are discussed, focusing on the sites occupied by the lanthanides. This is because the emission due to europium(II) of SrAl2O4:Eu,Ln (Ln: lanthanides) is significantly affected by such substitution. The EPR spectrum of SrAl2O4:Dy,Gd showed a pattern typical for two overlapping resonances of 8S7/2 state ions with a λ = ∣D/E∣ of ⅓, suggesting that the gadolinium(III) sites have very low symmetry.
