Abstract:Na5Eu(MoO4)4 is a stoichiometric host luminescent material. If H2WO4 and Na2WO4 are added as reactants in synthetic process of Na5Eu(MoO4)4, the Na5Eu(Mo1-xWxO4)4 system will be synthesised. When 0y=0.028. According to X-ray diffraction analysis, the reason of enhancement might be related to alpha cristobe-lite which is formed by added SiO2 and forms the encapsulation of Na5Eu(MoO4)4.
