The Mg₃/Al and Mg₃/AlEu layered double hydroxides (LDHs) were fabricated using a sol-gel chemistry approach and intercalated with different anions through ion exchange procedure. The influence of the origin of organic anion (oxalate, laurate, malonate, succinate, tartrate, benzoate, 1,3,5-benzentricarboxylate (BTC), 4-methylbenzoate (MB), 4-dimethylaminobenzoate (DMB) and 4-biphenylacetonate (BPhAc)) on the evolution of the chemical composition of the inorganic-organic LDHs system has been investigated. The obtained results indicated that the type and arrangement of organic guests between layers of the LDHs influence Eu luminescence in the synthesized different hybrid inorganic⁻organic matrixes. For the characterization of synthesis products X-ray diffraction (XRD) analysis, infrared (FTIR) spectroscopy, fluorescence spectroscopy (FLS), and scanning electron microscopy (SEM), were used.
采用溶胶-凝胶化学方法制备了Mg₃/Al和Mg₃/AlEu层状双氢氧化物（LDHs），并通过离子交换程序用不同阴离子进行插层。研究了有机阴离子（草酸盐、月桂酸盐、丙二酸盐、琥珀酸盐、酒石酸盐、苯甲酸盐、1,3,5-苯三甲酸（BTC）、4-甲基苯甲酸盐（MB）、4-二甲基氨基苯甲酸盐（DMB）和4-联苯丙酮酸盐（BPhAc））的来源对无机-有机LDHs体系化学成分演变的影响。所得结果表明，LDHs层间有机客体的类型和排列影响合成的不同杂化无机-有机基质中Eu的发光。使用X射线衍射（XRD）分析、红外（FTIR）光谱、荧光光谱（FLS）和扫描电子显微镜（SEM）对合成产物进行表征。
