Luminescent Properties of MgLaLiSi2O7:Eu3+ Phosphors via Sol-Gel Process

Article Preview

Abstract:

MgLaLiSi2O7:Eu3+ phosphors have been prepared through the sol-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°C. The results of XRD indicated that the phosphors crystallized completely at 1050°C. In MgLaLiSi2O7:Eu3+ phosphors, the Eu3+ shows its characteristic red (613nm, 5D07F2) emissions.
