چکیده انگلیسی
Gd2Mo3O9 phosphors with various Dy3+ concentrations were synthesized by a traditional solid-state reaction using Na2CO3 as a flux. The influence of reaction temperature and Dy3+-doping concentration on the crystal structure of the phosphors was examined by XRD (X-ray diffraction). The effect of Dy3+-doping concentration on the emissions of Mo–O bond and Dy3+ was experimentally investigated. The energy transfers between host and Dy3+ ions, and between Dy3+ ions were analyzed based on both the Van Uitert and I-H models. The chromatic properties of the phosphors were also discussed.
