Eu3+ exchanged FAU was reacted with MoO3 in the solid-state at 723K, giving a precursor. By calcining it at 1073K, different crystalline phases were derived depending on MoO3-loading levels. Scheelite type crystal of NaEu(MoO4)2 was formed at high MoO3-loading levels, whereas europium sodalite was formed at low loading levels. For the former sample, X-ray diffraction analysis and transmission electron microscopy revealed that the nanosized NaEu(MoO4)2 was dispersed homogeneously within amorphous aluminosilicate matrix originated from FAU. The amorphous particles containing NaEu(MoO4)2 maintained the original morphology, which the starting FAU particles possessed. The emission intensity of nanosized NaEu(MoO4)2 in the matrix was one order higher than that of europium sodalite. The emission lifetime of nanosized NaEu(MoO4)2 (0.39ms) in the matrix was longer than that of bulk NaEu(MoO4)2 (0.35ms) fabricated by conventional solid-state processes.
