A series of Ba 3 Lu(PO 4 ) 3 :Sm 3+ phosphors were prepared by traditional high temperature solid-state reaction methods. The site-preferred occupancy of Sm 3+ in Ba 3 Lu(PO 4 ) 3 and the luminescence properties of Ba 3 Lu(PO 4 ) 3 :Sm 3+ were studied combined with X-ray diffraction, photoluminescence excitation (PLE) spectra, and emission (PL) spectra as well as temperature-dependent PL and decay curves. The PL intensity is improved with increasing Sm 3+ content and the optimal dopant content is 0.05. The temperature-dependent PL spectra indicate that the emission intensity decreases with the temperature because of the enhancement of the non-radiative transition. The results indicate that these reddish-orange emitting phosphors could be for potential applications in w-LEDs.
