| 摘 要： | 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。

| Abstract: | SrZnO_2:Eu~(3+),Li~+ phosphor was synthesized by combustion method and its luminescent characteristics were investigated by XRD and FL.The results showed that Eu~(3+) and Li~+ were successfully doped into the crystal lattice of SrZnO_2 matrix and Eu~(3+) preferentially occupied Sr~(2+) asymmetry cationic sites,thus emitting 615 nrn red light originated form ~5D_0→~7F_2 transition.The emission spectrum intensity of SrZnO_2:Eu~(3+)phosphor was greatly increased by Li~+ as charge compensator.and the evolvement trend related with differem doping ratio of Eu~(3+) and Li~+. |
