摘　　要：Mnions were co-doped in yttrium aluminum garnet doped cerium(YAG:Ce) phosphors as a co-activator and host lattice element using the co-precipitation method.These ions broadened the emission spectra of the pure YAG:Ce phosphor,which is caused by the 2E-4A2,5E-5T2 or 1T2-5T2 transition.From our X-ray diffraction results,we observed that Ce3+(1.032 ) was substituted at the Y3+(0.900 ) site,and Mn4+(0.538 ) and Mn3+(0.67 ) were substituted at the Al3+(0.535 ) site.The chromaticity color co-ordinates of YAG:Ce0.06 is(0.203,0.167),and the indices of YAG:Ce0.06,Mn0.04 and YAG:Ce0.06,Mn0.08 are(0.249,0.181) and(0.233,0.194),respectively.The manganese co-doped yttrium aluminum garnet doped cerium blended with the YAG:Ce phosphor showed improved white light emission.Mn ions were co-doped in yttrium aluminum garnet doped cerium （YAG：Ce） phosphors as a co-activator and host lattice element using the co-precipitation method. These ions broadened the emission spectra of the pure YAG：Ce phosphor, which is caused by the ^2E-^4A2, ^5E-^5T2 or ^1Te-^5T2 transition. From our X-ray diffraction results, we observed that Ce^3＋ （1.032 A°） was substituted at the Y^3＋ （0.900A°） site, and Mn^4＋ （0.538 A°） and Mn^3＋ （0.67 A°） were substituted at the Al^3＋ （0.535 A°） site. The chromaticity color co-ordinates of YAG：Ce0.06 is （0.203, 0.167）, and the indices of YAG：Ce0.06,Mn0.04 and YAG：Ce0.06,Mn0.08 are （0.249, 0.181） and （0.233, 0.194）, respectively. The manganese co-doped yttrium aluminum garnet doped cerium blended with the YAG：Ce phosphor showed improved white light emission.
