摘要	Ba1-xMoO4:xEu(3+) red phosphors were synthesized by the co-precipitation method with NH4HCO3-NH3 center dot H2O system as the precipitating agent. X-ray diffraction (XRD), scanning electron microscope (SEM) and photoluminescence spectra were used to characterize the structures and luminescent properties of the phosphors. The results showed that introduction of Eu did not change the crystal structure and morphology of BaMoO4:Eu3+ phosphors. In addition, the influence of different contents of dopant Eu3+ for the luminescent properties of red phosphors Ba1-xMoO4:xEu(3+) was analyzed. Photoluminescence spectra showed a red emission around 612 nm with 395 and 465 nm excitations, which matches the output wavelength of ultraviolet and blue LED chips. The optimal doping concentration of the red phosphors Ba1-xMoO4:xEu(3+) was 30 mol%. (c) 2012 Elsevier B.V. All rights reserved.
