Abstract

Series samples of Sr₂CeO₄:Eu³⁺, M⁺ (M⁺ = Li⁺, Na⁺, K⁺) phosphors were successfully prepared by solid-state reaction method. As Charge compensators, Li⁺/Na⁺/K⁺ ions were added though non-stoichiometric (NSC) compensation and stoichiometric (SC) compensation, respectively. The phase composition and luminescence properties were investigated by X-ray diffraction (XRD), photoluminescence (PL) and fluorescent decay curves. The luminescence intensity was greatly enhanced by doping Li⁺/Na⁺/K⁺ ions with NSC compensation, and Na⁺ ions enhanced the luminescence intensities more obviously than Li⁺ and K⁺. Doping Li⁺/Na⁺/K⁺ results in improvement of energy transfer from Ce⁴⁺ to Eu³⁺ and lower symmetry of the structure.
