Eu2+-activated SrMg2Al16O27 novel phosphor was synthesized by a combustion method (550 degrees C furnace). The prepared phosphor was first characterized by X-ray diffraction (XRD) for confirmation of phase purity. SEM analysis showed the morphology of the phosphor. The photoluminescence characteristics showed broad-band excitation at 324 nm, which was monitored at 465 nm emission wavelength. The SrMg2Al16O27:Eu2+ phosphor shows broad blue emission centred at 465 nm, emitting a blue light corresponding to 4f(6)5d(1) -> 4f(7) transition. Here we report the photoluminescence characteristics of the prepared phosphor and compare it with commercial BAM:Eu2+ phosphor.
