摘要
采用溶胶/凝胶方法制备了一系列含有铽-水杨酸配合物的聚乙烯醇高分子杂化光功能材料,考察了偶联剂的引入对杂化材料的形貌和光学性能的影响。利用红外光谱表征材料的结构,扫描电镜和荧光光谱表征材料的性能。结果表明,随着偶联剂的引入,可以有效避免相分离现象和荧光淬灭,显著提高了杂化材料的光学性能。
A series of salicylic acid terbium/polyvinyl alcohol hybrid materials with different coupling agent contents were prepared by sol-gel method. The morphology and photophysical properties were investigated. Fourier transform infrared spectroscopic （FT-IR） was applied to characterize the structure of the obtained hybrid material, scanning electron microscope （gEM） and fluorescence spectra were applied to characterize the performance of the hybrid material. The result shows that the phase separation processes and the fluorescence quenching are avoided and the optical performance of hybrid materials is improved effectively
