Synthesis and Properties of Ca0.85(W1-xMOx)O4∶Eu0.15 Rare Earth Phosphors

摘要：

　　Rare earth phosphors of Ca0.85(W1-xMox)O4∶Eu0.15 (x=0.00-0.50) were synthesized via solidstate reaction in air.The lattice parameters strongly depended on the x value,which was analyzed by the XRD patterns.Microstructures of the powders were observed by SEM.The phosphors could be effectively excitated by ultraviolet (UV) light (250-300nm) and blue light (464nm),which were showed with the excitation and emission spectra.With the increasing ofx value,moreover,another emission peak of the sample which was excitated by UV light appeared and shifted to short wavelength,from 597 to 545 nm.The luminescence properties of the phosphors and energy transfer mechanism were also discussed.
