Özet

Mn4+, Ce4+ and Sm3+ doped MgAl2Si2O8-based phosphors were synthesized at 1300 degrees C by solid state reaction and characterized by thermogravimetry (TG), differential thermal analysis (DTA), X-ray powder diffraction (XRD), photoluminescence (PL), thermoluminescence (TL) and scanning electron microscopy (SEM). The phosphors showed broad red emission bands in the range of 610-715 nm and different maximum intensity when activated by UV illumination. Such a red emission can be attributed to the intrinsic E-2 -> (4)A(2) transitions of Mn4+.
