The influences of the flux KCl or KF on the XRD patterns, cell parameters, crystal morphology, and spectral properties of the phosphor LaMgB5O10∶Ce3+, Mn2+ are studied. The results indicate that as 4.2%, 8.6%, 12.8% KCl and 5.3%, 10.5% KF are added individually into the phosphor (La0.85Ce0.15) (Mg0.9Mn0.1) B5O10, some peaks of the XRD patterns are intensified and cell volumes are decreased. A small amount of Cu mono-crystal typed phase appears as more than 5% KCl is added. There are six hexagonal crystal-faces and eight triangular crystal-faces attributed to the {100} and {111} respectively. When 15% KCl is added into the phosphor, multi-faced regular crystals are formed and the crystal self-regulation appears. The emission intensity of 5d→4f ((（）2F5/2,) (（）2F7/2)) of Ce3+ and （（）4G→（）6S） of Mn2+ increases up 3.41 and 2.36 times respectively.
The photoluminescence glass fiber in Eu3+ doped ZnO-MgO-CdO-B2O3 is drawn artificially by high-temperature solid state reaction and glass stream hauling method in handling of photoluminecent waste material. Its diameter is 0.01～0.30 mm and its length is more than 10 m. The strong emission band of Eu3+ at 613 nm belongs to （（）5D0→（）7F2） electric dipole transition, and the emission intensity at 591 nm is 40% of that at 613 nm and intensity belongs to （（）5D0→（）7F1） magnetic dipole transition. It is known to all that Eu3+ mainly hold asymmetrical center lattice in local ambient and also possesses symmetrical center lattice. By fitting decay curves of Eu3+ of different concentrations, it is discovered that the luminescence changes from the first order decay to the second order decay while the concentrations of Eu3+ are increased. It is observed by SEM that glass fiber shows smooth surface, low crystal growing rate, high density of fracture and shellfish veins of fracture obviously submits ditch form. Meanwhile, a series of mechanics parameters were measured and the spectral behaviors of the glass fiber in Eu3+ doped ZnO-MgO-CdO-B2O3 were studied.
