Rare-earth ions doped luminescent materials have excellent optical properties and low energy consumption, which are widely used in optoelectronic devices. In this work, Sm 3+ -doped Ba 0.5 Sr 0.5 TiO 3  perovskite phosphors were prepared by a convenient high-temperature solid-reaction method. A strong orange-red luminescence appeared at 600 nm, corresponding to the energy-level transition of  6 H 5/2  →  4 F 7/2 . The optimal concentration of Ba 0.5 Sr 0.5− x  TiO 3 :  x Sm 3+  was determined to be around  x  = 0.08. The forbidden band width and the fluorescence lifetime of Ba 0.5 Sr 0.5 TiO 3 : Sm 3+  are 3.15 eV and 2.7 μs, respectively. The CIE coordinates are (0.509, 0.476). The as-prepared orange-red perovskite phosphors are expected to be used in white light–emitting diode (LED) devices.
