A series of phosphors were synthesized by solid-state reactions. The emission peaks of is blue shifted front 605 to 570 nm with increasing Sr content. Since . Mn phosphors exhibit strong absorption in region of 254 nm, the emission wavelength of a fluorescent lamp, these phosphors can be used as wavelength tunable emitting phosphors from reddish orange to yellow. We investigated the optical and structural properties of phosphors.
