采用燃烧法合成了SrZnO2:Eu3+,Li+发光材料,用X射线衍射谱、荧光光谱对样品进行了表征。结果表明,Eu3+和Li+成功掺入SrZnO2基质中,Eu3+离子在基质中主要占据Sr2+离子不对称性格位,发射来源于5D0→7F2615nm为主的红光。加入电荷补偿剂Li+离子的掺入能显著提高发光强度,其影响程度与Eu3+、离子和Li+离子的掺杂比例密切相关。
The SrZnO2: Eu3 + and Li + phosphors were synthesized by combustion method. The samples were characterized by X-ray diffraction and fluorescence spectroscopy. The results show that Eu3 + and Li + are successfully incorporated into the SrZnO2 matrix. The Eu3 + ions mainly occupy the asymmetric lattice sites of Sr2 + in the matrix and emit red light mainly from 5D0 → 7F2615nm. Incorporation of charge compensator Li + ions can significantly improve the luminescence intensity, the degree of influence is closely related to the doping proportion of Eu3 + ions and Li + ions.
