The cerium luminescence in SrY2O4 shows two bands emitting in the blue and green regions of the optical spectrum. Based on standard emission and excitation spectroscopy combined with time-resolved emission studies, we can attribute the blue emission to a Ce3+ 5d-4f transition and tentatively assign the green emission to a Ce4+-O2-charge transfer transition.
