Preparation and Properties of Europium-Mixed Molybdate Luminescent Aterials
Gadolinium oxide(Gd2O3),europium oxide(Eu2O3),ammonium molybdate(H8MoN2O4),citric acid(C4H2O2)were used as raw materials,Gd2(MoO4)3∶Eu3+luminescent material were prepared by ultrasound-assisted gel-gel method.The effects of Eu ion molar number and whether they were calcined are discussed.Materials were characterized and ana-lyzed using X-ray diffractor(XRD),scanning electron microscope(SEM)and Fluorescence spectrometer(LS).The re-sults show that:with the optimal excitation at 403 nm,the emission peaks of the material are located between 470 and 530 nm,the amount of Eu ionic and whether calcined affect the morphology and luminescente properties of the material.
