Eu(2+) doped M(2)B(5)O(9)Cl(M=Ca Sr) phosphors were prepared by a solid-state reaction method Luminescent properties of as-synthesized phosphors were investigated under the excitation of near-ultraviolet (n-UV) light Photoluminescence (PL) spectra revealed a blue emission band and the emission band shifted to a longer wavelength region as Ca(2+) substituted Sr(2+) The photoluminescence excitation (PLE) spectra of M(2)B(5)O(9)Cl Eu(2+) (M=Ca Sr) showed broadband absorptions in the n-UV region Moreover the as-prepared phosphors were also compared with commercial BaMgAl(10)O(17) Eu(2+) (BAM) blue phosphor The present phosphors showed a narrower full width at half-maximum and higher PL intensity than the reference BAM under the n-UV light excitation (C) 2010 Elsevier B V All rights reserved
