O以不同的质量分数引入到PVA基质中,在交联剂硼酸的作用下形成荧光凝胶。利用FTIR、PL、DSC、TGA等对其结构、发光性能及其热性能进行了研究。FTIR结果表明,铽配合物成功地掺杂到了PVA凝胶体系中。荧光发射光谱表明,所有铽配合物的PVA荧光凝胶都具有很好的荧光性能,更重要的是掺杂了3%、5%、7%铽配合物的PVA荧光凝胶位于545 nm处的特征发射峰的发射强度相比于小分子铽配合物Tb(ACAC)

O的发射强度更高,分别是其2.15、3.27和5.65倍。表明PVA基质对铽配合物具有较好的敏化作用。此外,DSC和TGA研究结果表明,铽配合物的引入使得PVA凝胶的热稳定性略有下降,但影响不大。

the PVA fluorescence gels with terbium complex all have good fluorescence properties. Especially
the emission intensity at 545 nm of PVA fluorescent gel is higher than the precursor Tb(ACAC)

the DSC and TGA results indicate that the introduction of terbium complex has little decrease for the thermal stability of PVA fluorescence gel.
