摘要

采用高温固相法结合电荷补偿方式2Sr 2+→Eu3++Na +，合成了适合白光LED的红色荧光材料Nax Sr1-2x MoO4：Eux3+ ( =0．1、0．15、0．2，0．25、0．3)系列样品．对样品分别进行了x射线衍射(XRD)分析和荧光光谱的测定．测试结果表明，N Sr MoO ：Eu：荧光粉可以被近紫外光(uV)(393 nm)和蓝光(463 nm)有效激发．通过探讨Na+ 和Eu3+ 的掺杂浓度对发光强度的影响，得出Nax Sr1-2x MoO4：Eux3+系列样品的发光强度比SrMoO4：Eu3+明显增加，且当掺杂量 =0．2时，Nax Sr1-2x MoO4：Eux3+列样品在616 nm处的发光强度最大．分析了Nax Sr1-2x MoO4：Eux3+系列样品在380 nm紫外光激发下的色坐标，当Na 和Eu 的掺杂量 =0．15时，样品的红色显色最强．

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．
