چکیده انگلیسی
LiLa(MoO4)2: Dy3+ and LiLa(MoO4)2: Dy3+, Eu3+ phosphors were successfully synthesized by conventional solid state reaction method. The crystal structure, luminescent properties and energy transfer mechanism of the samples were researched. The optimal Dy3+ doping concentration of LiLa(MoO4)2 (LLM) excited by ultraviolet was 5Â mol%. Upon 454Â nm excited, the energy transfer mechanism between Dy3+ and Eu3+ in co-doped LLM phosphors was identified as dipole-dipole interactions. The energy transfer efficiency from Dy3+ to Eu3+ and the CIE coordinates of LLM: Dy3+, Eu3+ crystals have been calculated. The results show that the energy transfer from Dy3+ to Eu3+ in the system is efficient and the sample colors are changed in the greenish yellow region.
