Mn-ion-enhanced red spectral emission from yttrium aluminum garnet doped cerium phosphor

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 1T2-5T2 transition. From our X-ray diffraction results, we observed that Ce3+ (1.032 Å) was substituted at the...
