摘要：

MgLaLiSi2O7:Eu3+ phosphors have been prepared through the sot-gel process. X-ray diffraction (XRD), thermogravimetric and ddifferential thermal analysis (TG-DTA), FT-IR spectra and photoluminescence spectra were used to characterize the resulting phosphors. FT-IR spectra suggested that crystallized silicates have formed in the powders annealed at 1050 degrees C. The results of XRD indicated that the phosphors crystallized completely at 1050 degrees C. In MgLaLiSi2O7:Eu3+ phosphors, the Eu3+ shows its characteristic red (613nm, D-5(0)-F-7(2)) emissions.
