Abstract: Nax Sr1-2x MoO4：Eux3+ ( ：0．1、0．15、0．2、0．25、0．3)red phosphors for white LEDs were synthesized by using the high temperature solid state reaction and charge compensation．and 2Sr¨ Eu” +Na was studied as well．The samples were characterized by means of X-ray diffraction and photoluminescence spectra．The results indicate that Nax Sr1-2x MoO4Eux3+phosphors can be excited efectively by 393 nm and 463 nln lights．Compared with SrMoO4：Eu3+，the emission intensity of Nax Sr1-2x MoO4：Eux3+is increased obviously．As regards the influence of Eu3+ and Na concentrations on the luminescent property，the highest emission intensity on the 61 6nm is exhibited when is 0．2．Moreover，it analyzes the CIE chromaticity( ，Y)of Nax Sr1-2x MoO4：Eux3+ excited by 380 nm lights．When the doping is 0．15 phosphors of the samples turn from pink to red．

Key words: Eu3+；red phosphor；molybdate；charge compensation；CIE chromaticity
