Luminescence properties
Fig. 5 shows radioluminescence spectra of the Ce doped SHO/
SAO eutectic sample. The peaks in the wavelengths of 410 nm
are attributed to Ce3+ 5d–4f transitions in SHO according to the
previous reports [11–13]. Ce3+ 5d–4f emission of Ce doped SAO
at 310 nm reported by other groups [16,17] was not detected.
Fig. 6 shows excitation and emission spectra of the eutectic sample.
