Abstract

In order to improve SrAl2O4: Eu2+, Dy3+ luminescent properties, explore Eu2+ and Dy3+ in SrAl2O4, using a plane-wave ultrasoft pseudopotential method under the density functional theory framework, were established SrAl2O4, SrAl2O4: Eu2+ and SrAl2O4: Eu2+, Dy3+ supercell model, and calculated their population numbers, band structure and density of states. The results showed that: the luminescence center Eu2+ doping SrAl2O4 makes impurity level appearing in the forbidden band and the conduction band, and produce photoluminescence effect. On this basis, the auxiliary activator Dy3+ doping makes the luminous intensity higher, persistence time longer.
