Abstract

Gd₂O₂S co-doped Tb³⁺, Yb³⁺ and Er³⁺ phosphors were prepared by coprecipitation method, and their luminescence intensity and fluorescence lifetime were studied. The effects of doping concentration of Tb³⁺ ion, (1 mol % - 11 mol %) Tb³⁺ and Yb³⁺ doping ratio (1:1 - 1:6) and doping concentration of Er³⁺ ion (0.1 mol % - 1.1 mol %) on the properties and fluorescence lifetime of synthesized Tb³⁺, Yb³⁺ and Er³⁺ Gd₂O₂S phosphors were investigated. The phase analysis of Gd₂O₂S:Tb³⁺, Yb³⁺, Er³⁺ phosphors were studied by X-ray powder diffraction (XRD). The fluorescence characteristics of Gd₂O₂S:Tb³⁺, Yb³⁺, Er³⁺ phosphors were studied in terms. In this work energy transfer mode of Gd₂O₂S:Tb³⁺, Yb³⁺, Er³⁺ phosphors were studied, which provided a proof for the study of the up-conversion system mechanism.
