ABSTRACT

A novel Ce3+ doped Lu3MgAl3SiO12 phosphor (Lu2.94Ce0.06MgAl3SiO12) was successfully synthesized by a conventional solid-state reaction at 1450oC for 5 h. The crystal structure of the synthesized phosphor powder was characterized by X-ray diffraction and Rietveld refinement. The prepared phosphor powder showed a broad peak at 550 nm, and the temperature dependence on photoluminescence properties of the prepared Lu2.94Ce0.06MgAl3SiO12 phosphor was investigated from 300 to 525 K. The activation energy for thermal quenching was determined by Arrhenius fitting. The experimental results clearly indicate that prepared Lu2.94Ce0.06MgAl3SiO12 phosphor has great potential for a down-conversion yellow phosphor in white light-emitting diodes.
