为更好地提高稀土配合物的发光性能,采用非共价方法制备了一种新型的高发光性能材料。发现苯甲酸(BA)和1,10-邻菲咯啉水合物(Phen)与Sm3+和La3+配位形成异核稀土络合物。通过傅立叶变换红外光谱、X射线电子光谱、荧光光谱、有机元素分析仪和紫外光谱等手段对制备的产物进行表征。结果表明:复合材料具有较强的发光强度、较长的使用寿命和较好的热稳定性。此外,La3+离子对材料有很强的敏化作用,对提高材料的发光强度有显著作用。然后利用单因素实验和响应曲面相结合的方法对实验进行优化。
Goal:a novel material with high luminescent performance was prepared using a noncovalent approach.Process and method:herein,a heteronuclear rare earth complex was revealed in which the benzoic acid (BA) and 1,10-phenanthroline hydrate (Phen) coordinated with Sm3+ andLa3+.The as-prepared products were characterized via fourier-transform infrared spectroscopy,X-ray electron spectroscopy,fluorescence spectrometer,organic elemental analyzer,ultraviolet spectrometer and thermogravimetric analysis.Result and conclusion:the hybrid materials exhibited strong luminescence intensity,long lifetime and good thermal stability.Besides,La3+ ions had a strong sensitizing effect on materials and played a significant role in improving the luminescence intensity.Then the experiment was optimized by combining the single-factor experiment with the response surface.
