摘要：

The Eu3+-activated double molybdate red phosphor, LiEuMo2O8 was prepared by a sot-gel process using inorganic salts as starting materials. A precursor prefired at 500 degrees C for 240 min was subsequently annealed at 600 degrees C for 240 min in Ar. The crystal structure, surface morphology and luminescent properties were analyzed by an X-ray diffractometer, a field emission scanning electron microscope and a fluorescent spectrophotometer. The obtained LiEuMo2O8 shows a strong excitation band near 395 and 466 nm and intensely red-emission lines at 616 nm corresponding to the D-5(0) -> F-7(2) transitions on Eu3+ at 395 nm of light excitation.
