Eu 2+ ‐activated SrMg 2 Al 16 O 27 novel phosphor was synthesized by a combustion method (550°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 SrMg 2 Al 16 O 27 :Eu 2+ 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:Eu 2+ phosphor. Copyright © 2011 John Wiley & Sons, Ltd.
