Photoluminescence glass fibers of Eu~(3+)-doped ZnO-MgO-CdO-B_2O_3 was drawn artificially be high-temperature solid state reaction and glass stream hauling method in handling of photoluminescence waste material. Its diameter was 0.01～0.30 mm and length was more than 10 m. The strong emission band of Eu~(3+) at 613 nm belongs to (()~5D_0-()~7F_2) electric dipole transition, and the emission intensity at 591 nm equivalent to that at 613 nm belongs to (()~5D_0-()~7F_1) magnetic dipole transition. It is known that Eu~(3+) mainly occupies asymmetrical center in lattice in local ambient but also occupies symmetrical center in lattice. By fitting decay curves of Eu~(3+) with different concentrations, it is discovered that the luminescence changes from the first order decay to the second order decay while the concentrations of Eu~(3+) are increased. It is observed by SEM that glass fiber has smooth surface, low crystallization, high density of fracture and shellfish veins of fracture obviously submits ditch form. A series of mechanical parameters were measured and the spectral behaviors of the glass fiber of Eu~(3+) doped ZnO-MgO-CdO-B_2O_3 were studied.
