Abstract:
Li2Y4-xEux(WO4) 7-y(MoO4)y red-emitting phosphors were synthesized by solid state reaction and characterized by powder X-ray diffraction (XRD) and photoluminescence (PL) spectrum. The excitation spectra showed that the phosphors could be efficiently excited by near-UV light of 395 nm. When the relative molar ratio of Mo/W was 7:0, and the optimum doped concentration of Eu3+ was 2.8 mol, the phosphor showed strong red emission lines at 615 nm corresponding to the forced electric dipole 5D0→7F2 transition of Eu 3+. Compared with Na2Y2Eu2(MoO 4)7 and K2Y2Eu2(MoO 4)7, the fluorescence intensity of Li2Y 1.2Eu2.8(MoO4)7 phosphor was the strongest. The CIE chromaticity coordinates of Li2Y 1.2Eu2.8(MoO4)7 phosphor was calculated to be (0.66, 0.34). © 2013 The Chinese Society of Rare Earths.
