Using rare earth ions to improve the luminescence properties of defect-related luminescent material Zn3Al2Ge2O10

Abstract

Zn3Al2Ge2O10 are synthesized by a high-temperature solid-state method, and a weak white emission ranging from 350 to 600 nm is observed. In order to enhance the white emission intensity of Zn3Al2Ge2O10, the rare earth ions (Eu3+, Ce3+, Dy3+, Tb3+) are introduced into Zn3Al2Ge2O10. The results show that the white emission intensity of Zn3Al2Ge2O10 is enhanced by doping rare earth ions, which is ascribe to the increased oxygen vacancy V’’o. Especially, Eu3+ ions can effectively enhance the white emission intensity of Zn3Al2Ge2O10, comparing to the other rare earth ions (Ce3+, Dy3+, Tb3+) doped Zn3Al2Ge2O10, and the intensity has maximum when doping concentration reaches 0.06. The results indicate that the luminescence properties of defect-related luminescent material Zn3Al2Ge2O10 can be improved by doped rare earths ions.
