Flower-like Y-2(MoO4)(3):Dy3+ phosphors have been synthesized via a co-precipitation approach with the aid of beta-cyclodextrin. The crystal structure and morphology of the phosphors were characterized by XRD (X-ray diffraction) and FE-SEM (field emission scanning electron microscopy), respectively. The excitation and emission properties of the phosphors were examined by fluorescence spectroscopy. The dependence of color coordinates on the Dy3+ doping concentration was analyzed. The energy transfer mechanism between Dy3+ ions was studied based on the Huang's theory, I-H and Van Uitert's models. It was concluded simultaneously from these three routes that the electric dipole-dipole interaction between Dy3+ ions is the main physical mechanism for the energy transfers between Dy3+.
