摘要：

Novel Eu3+ doped zirconate garnet-type ceramics, Li 7(La3-xEux)Zr2O12 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 5D 0→7F2 emission transition of Eu 3+ were studied in detail. The results indicate that there exists efficient energy tran...
