Mn4+, La3+ and Ho3+ doped MgAl2Si2O8-based phosphors were first synthesized by solid state reaction. They were characterized by thermogravimetry (TG), differential thermal analysis (DTA), X-ray powder diffraction (XRD), photoluminescence (PL) and scanning electron microscopy (SEM). The phosphors were obtained at about 1300 degrees C. They showed broad red and fuchsia-pink emission bands in the range of 610-715 nm and had a different maximum intensity when activated by UV illumination. Such a fuchsiapink emission can be attributed to the intrinsic d-d transitions of Mn4+. (C) 2011 Elsevier B.V. All rights reserved.
