They were characterized by thermogravimetry, differential thermal analysis, X-ray powder diffraction, photoluminescence, and scanning electron microscopy. The luminescence mechanism of the phosphors, which showed broad red emission bands in the range of 600-715 nm and had a different maximum intensity when activated by UV illumination, was discussed. Such a red emission can be attributed to the E-2 -> (4)A(2) transitions of Mn4+.enInorganic CompoundsLuminescenceThermogravimetry (TG)X-Ray DiffractionElectron MicroscopyArticle1172573578info:eu-repo/semantics/closedAccess2-s2.0-84904473888WOS:00033934130000610.1007/s10973-014-3791-6Q1Q2
