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.
