  • Spheroidal Ca(MoO4)1-x(WO4)x:Eu3+ of red phosphors were synthesized by microwave assisted liquid precipitationmethod when urea was used as a precipitator. The crystal structure, surface morphology and luminescent properties of the samples were characterized by XRD, SEM, and photoluminescence spectroscopy (PL). It is found that Ca(MoO4)1-x(WO4)x:Eu3+ red phosphors prepared have complete crystal form, high purity and scheelite structure. The introduction of WO42- would improveluminous efficiency of samples, and when the doping mole fraction of WO42-is 0.4, the relativeluminous intensity of the main emission peak at 616 nm reaches maximum under the excitation of 395 nm. However, the concentration of quenching phenomenon will occur when WO42-doping concentration is more than 0.4. The optimum of calcining temperature is 1 000 ℃, and calcination time is 4 h.
