Novel Eu 3+ doped zirconate garnet-type ceramics, Li 7 (La 3−x Eu x )Zr 2 O 12 with x=0, 0.001–1.0, have been synthesized by solid state reaction and the purity phase of the samples was checked by XRD. Room temperature steady and time-resolved emission spectra, under UV and visible light excitation energy, have been investigated. The concentration effect on the quenching blue emission, due to the Zr–O charge transfer transition and 5 D 0 → 7 F 2 emission transition of Eu 3+ were studied in detail. The results indicate that there exists efficient energy transfer from host to Eu 3+ . The mechanism of interaction between Eu 3+ ions has also been investigated by means of the Inokuti–Hirayama model.
