Abstract

Herein, Zn3Al2Ge2O10 was synthesized by a high-temperature solid-state method, and a weak white emission ranging from 350 to 600 nm was observed. To enhance the white emission intensity of Zn3Al2Ge2O10, rare earth ions (Eu3+, Ce3+, Dy3+, and Tb3+) were introduced into Zn3Al2Ge2O10. The results show that the white emission intensity of Zn3Al2Ge2O10 is enhanced by doping rare earth ions, which is ascribed to the increased oxygen vacancy Image ID:c7nj00181a-t1.gif. Especially, Eu3+ ions can effectively enhance the white emission intensity of Zn3Al2Ge2O10 as compared to other rare earth ions (Ce3+, Dy3+, and Tb3+) when doped in Zn3Al2Ge2O10, and the intensity is maximum when the doping concentration reaches 6 mol%. The results indicate that the luminescence properties of the defect-related luminescent material Zn3Al2Ge2O10 can be improved by doping rare earths ions.
