SrZnO2:Sm3+红色荧光体的低温燃烧合成及发光性能研究

Abstract

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 Sm^3+.An emission at wavelength of 605 nm orange-red light originated from ⁵G_5/2 to ⁶H_7/2 was observed. Meanwhile,the concentration quenching of SrZnO₂:Sm³⁺ appeared in different degrees.

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