摘要/Abstract

摘要： 采用低温燃烧法合成了SrZnO₂:Sm³⁺红色荧光体，用X射线衍射谱及荧光光谱对样品进行了结构表征和发光性能研究。结果表明，Sm3+成功地掺入到SrZnO₂基质中，所得样品为正交晶系结构的SrZnO₂物相，Sm³⁺在SrZnO₂基质中主要占据Sr²⁺不对称性格位，发射来源于⁵G_5/2→⁶H_7/2605 nm为主的橙红色光，同时存在不同程度的浓度猝灭。

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
