Sm 3+ doped Na 3 MgZr(PO 4 ) 3 phosphor was prepared using high temperature solid state reaction and characterized through X-ray diffractometer (XRD) to identify the crystalline phase. The site occupation of Sm 3+ in Na 3 MgZr(PO 4 ) 3 was discussed based on the XRD and crystal structure analysis. The photoluminescence emission spectra showed that Na 3 MgZr(PO 4 ) 3 :Sm 3+ could absorb near-ultraviolet light around 403 nm and emit red emissions with dominated peaks at 600 and 647 nm, ascribed to the 4 G 5/2 to 6 H 7/2 or 6 H 9/2 transitions of Sm 3+ ions, respectively. The optimal doping concentration, the critical distance as well as the interaction mechanism of Sm 3+ in Na 3 MgZr(PO 4 ) 3 were discussed. Moreover, the temperature dependent luminescent properties were measured and revealed that Na 3 MgZr(PO 4 ) 3 :Sm 3+ had excellent thermal stability.
