Nanocrystalline europium-doped AZrO(3) (A=Ca, Sr, Ba) were prepared by Pechini-type complex sol-gel method. The attained results of XRD and SEM suggest that this synthesis method appears to be an efficient method to prepare the luminescence materials AZrO(3):Eu with high homogeneity and purity. At the same time, the photoluminescence results indicate that Eu3+ ions in monoclinic CaZrO3 have the worst symmetry among these phosphors. Furthermore, CaZrO3:Eu exhibit the strongest luminescent intensity and pure red color which show that this phosphors may be more possible to be regarded as a promising candidate for applications in displays.
