The LiSr 4 (BO 3 ) 3 :Dy 3+ phosphors were synthesized in air by solid-state reaction route. The as-synthesized phosphors were characterized by X-ray powder diffraction (XRD), photoluminescence excitation (PLE) and photoluminescence (PL) spectra. The PLE spectra show the excitation peaks from 300 to 400nm is due to the 4f–4f transitions of Dy 3+ . This mercury-free...
