Abstract

A novel Ce³⁺-doped Lu₃MgAl₃SiO₁₂ (LCMAS) phosphor was successfully synthesized by a conventional solid-state reaction. The crystal structure of the LCMAS was characterized by Rietveld refinement. The broad emission spectra of the LCMAS were observed at 550 nm, and the temperature dependence on photoluminescence properties of the LCMAS was investigated. Also, the activation energy for thermal quenching was determined by Arrhenius fitting. The experimental results clearly indicate that the LCMAS phosphor has a great potential for the down-conversion of yellow phosphor into white light-emitting diodes.
