Copper-like GdF_3: Eu~(3+)hollow rings have been successfully prepared by a template-free,facile and lowcost hydrothermal method with Gd( NO_3)_3·6H_2O,KBF_4 as reaction source and Eu( NO_3)_3·6 H_2 O as the doped ions source. The products are fully characterized by PXRD,SEM,TEM and EDX. The results show that the copperlike GdF_3: Eu~(3+)hollow rings are hexagonal phase with the diameters of 500 nm. The influential factors of reaction time on the morphology and dosage of dopedions on the luminescence intensity have been investigated,respectively. When doping concentration of Eu~(3+)is 15%,the intensity of luminescence is the most strongest. Magnetism investigation shows that the GdF_3: Eu~(3+)is a kind of typical paramagnetic material.
