| 摘 要： | 本文采用水热法合成了NO-3型层状铕氢氧化物(NO3-LEuH),通过离子交换法将去质子的香豆素-3-羧酸和1-辛烷磺酸根离子引入前体LEuH的层间,改变香豆素-3-羧酸和1-辛烷磺酸钠的比例得到了一系列发光强度不同的复合体.采用X-射线粉末衍射仪(XRD),红外吸收光谱仪(IR),和荧光分光光度计(PL)等方法研究了其结构及性质,结果表明香豆素-3-羧酸的插入能有效敏化层板Eu3+的红光发射.

| Abstract: | The NO3-type layered europium hydroxide (NO3-LEuH )was synthesized by hydrothermal method.The organic compounds of coumarin-3-carboxylic acid (C3C)deprotonated by NaOH and 1-octane sulfonic acid sodium (OS)were intercalated into gallery of LEuH via an ion exchange method.Different molar ratios of organic guests (C3C/OS)gave rise to composites with different emission intensity.The as-formed composites were characterized by XRD,FT-IR and PL.PL spectra indicate that organic sensitizer of C3C can markedly enhance red luminescence of layer Eu3+ ions due to efficient energy transfer between C3C and Eu3+ions. |
