Langbeinite-type K2Bi1-xZr(PO4)3:xSm3+ phosphors were synthesized by a conventional solid-state reaction. The samples were characterized by X-ray diffraction, ultraviolet visible diffuse reflectance spectroscopy, calculation based on the density functional theory (DFT), and photoluminescence spectroscopy. The DFT analysis reveals that K2BiZr(PO4)3 is an insulator with an indirect band gap of 4.26 eV, which can be used as a fluorescent host. The prepared phosphors can be efficiently excited by near-ultraviolet light in the region from 340 to 425 nm and show three dominant emission bands peaking at 562, 600 and 647 nm due to the 4G5/2→6HJ (J = 5/2, 7/2, and 9/2) transition of the Sm3+ activator, respectively. The optimum doping concentration of Sm3+ is 10% (in mole). It is expected that Sm3+-doped K2BiZr(PO4)3 can be used as an orange-reddish phosphor for illumination or displays.
