采用水热法合成了改性MCM-41中孔分子筛;采用液相沉淀法合成了Eu(Phen)2(Pht)2Cl.H2O和Eu(Phen)2(Sal)(Pht)Cl.H2O两种稀土有机配合物。并将所制备的稀土有机配合物组装到改性MCM-41中,合成了稀土配合物(铕)/改性MCM-41杂化发光材料,采用小角XRD、红外光谱、荧光光谱和TEM、N2吸附-脱附对其结构和荧光性质进行了研究。结果表明,组装体具有MCM-41典型结构并且在组装之后仍保留了MCM-41的孔道结构;其荧光光谱具有Eu3+的特征荧光发射,发光强度大于纯配合物,更有利于实际应用。
The modified MCM-41 mesoporous molecular sieves were synthesized by hydrothermal method. Two kinds of Eu (Phen) 2 (Pht) 2Cl.H2O and Eu (Phen) 2 (Sal) (Pht) Cl.H2O were synthesized by liquid- Rare earth organic complexes. The rare earth complex (europium) / modified MCM-41 hybrid luminescent material was synthesized by the assembly of the prepared rare earth organic complex with modified MCM-41. Small angle XRD, infrared spectroscopy, fluorescence spectroscopy and TEM, N2 Adsorption - desorption of its structure and fluorescence properties were studied. The results show that the assembly has the typical structure of MCM-41 and still retains the pore structure of MCM-41 after assembly. The fluorescence spectrum has the characteristic fluorescence emission of Eu3 + and the luminescence intensity is greater than that of the pure complex, which is more practical.
