One‐dimensional nanowires of 8‐hydroxyquinoline strontium (SrQ₂‐1) was synthesized by liquid phase method. The structure and composition of the products were analyzed by X‐ray diffraction (XRD), Fourier transform infrared (FTIR) absorption spectroscopy, and X‐ray photoelectron spectroscopy (XPS), indicating that 8‐hydroxyquinoline strontium was successfully synthesized. The fluorescence properties of SrQ₂‐1 were analyzed by fluorescence spectra; the results showed that the maximum emission wavelength was detected at 473 nm (blue light area), the fluorescence lifetime of SrQ₂‐1 is 7.38 nanoseconds, and the fluorescence quantum yield is 28.3%. The analysis of TG‐DSC diagram suggests that SrQ₂‐1 begins to decompose at 475°C, which indicates SrQ₂‐1 has good thermal stability. Consequently, 8‐hydroxyquinoline strontium can be used as a blue luminescent material.

水介质中双（8-羟基喹啉）锶（SrQ2）的合成与表征

8-羟基喹啉锶一维纳米线（SRQ ₂ -1）通过液相法合成。通过X射线衍射（XRD），傅立叶变换红外（FTIR）吸收光谱和X射线光电子能谱（XPS）分析了产物的结构和组成，表明成功合成了8-羟基喹啉锶。通过荧光光谱分析了SrQ ₂ -1的荧光性质。结果表明，最大发射波长为473 nm（蓝光区域），SrQ ₂ -1的荧光寿命为7.38纳秒，荧光量子产率为28.3％。TG-DSC图分析表明，SrQ ₂-1开始于475℃，这表明SRQ分解₂ -1具有良好的热稳定性。因此，8-羟基喹啉锶可以用作蓝色发光材料。
