Doping Eu2o3 and CeO2 in LiNbO3, Ce:Eu:LiNbO3 crystal was successfully grown by the Czochralski method. The lattice constants of Ce:Eu:LiNbO3 were calculated. For the reason of volume compensation effect, that lattice constants of Ce:Eu:LiNbO3 were smaller than that of Ce:LiNbO3 and Eu:LiNbO3. It was found in the absorption spectra that the absorption band of Ce:Eu:LiNbO3 has the most red shift, and this phenomenon was explained. The response time of 32s, refractive efficiency of 75% and exponential gain coefficient of 22cm(superscript -1 of Ce:Eu:LiNbO3 was obtained by the holographic method. In the end, using Ce:Eu:LiNbO3 as storage medium, the holographic associative storage was realized and the clear and integrated retrieval graph was obtained.
