In this work, a novel sodium-fluorescent crystal (Na-FS) was synthesized from 4-dimethylaminobenzoic acid and sodium hydroxide by one-pot hydrothermal method. The structure and conformation of Na-FS were confirmed by single-crystal X-ray diffraction and scanning electron microscope, and the optical properties were studied by fluorescence spectrometer. The results showed that: Na-FS was a triclinic crystal, space group was P-1, cell parameters , and were 10.5113(3), 15.9198(5) and 15.9560(5) Å, respectively, and the number of independent atoms in a structure cell was two. Additionally, Na-FS has a blue fluorescence emission (around 360 nm under excited at the range of 230-300 nm) with great photostability and photobleaching resistance, and the quantum yield of Na-FS is 30.58%.
在本工作中，通过一锅水热法由4-二甲基氨基苯甲酸和氢氧化钠合成了一种新型钠荧光晶体（Na-FS）。通过单晶X射线衍射和扫描电子显微镜确定了Na-FS的结构和构象，并通过荧光光谱仪研究了其光学性质。结果表明：Na-FS为三斜晶体，空间群为P-1，晶胞参数a、b和c分别为10.5113(3)、15.9198(5)和15.9560(5) Å，一个晶胞中独立原子数为两个。此外，Na-FS具有蓝色荧光发射（在230 - 300 nm激发范围内，发射波长约为360 nm），具有良好的光稳定性和抗光漂白性能，Na-FS的量子产率为30.58%。
