Abstract: Red-emitting  SrZnO2:Sm3+phosphors were prepared by low-temperature combustion synthesis(LCS) and characterized by X-ray diffraction patterns(XRD) and photoluminescence(PL) spectrum.Crystal structure and luminescent properties were also investigated.Results showed the crystal structure of SrZnO2:Sm3+ was in the orthorhombic system;Sm3+ were successfully doped into the crystal lattice of SrZnO2 matrix and Sr2+ asymmetry cationic sites were preferentially occupied by Sm3+.An emission at wavelength of 605 nm orange-red light originated from 5G5/2 to 6H7/2 was observed. Meanwhile,the concentration quenching of SrZnO2:Sm3+ appeared in different degrees.

Key words: low-temperature combustion synthesis, SrZnO2:Sm3+, phosphor, luminescent properties
