Synthesis and luminescence properties of ZnO:Eu3+ nano crystalline via a facile solution method

Different ZnO:Eu3+ nanocrystalline were obtained from a facile solution method with two different precipitators. The comparison of photoluminescence property of two different ZnO:Eu3+ nanocrystalline was performed. The XRD patterns and the PL spectra indirectly indicate that the dopant Eu3+ ions had entered into the crystal lattices of ZnO. The study on the PL spectra of the as-prepared ZnO:Eu3+ nanocrystalline shows that with the change of dopant concentration, the ratio of relative emission intensity of electric dipole transition to magnetic dipole transition changes, which fully expresses that the presence of the inversion centers is associated with the dopant concentration of Eu3+.
