| 摘 要： | 合成了一种新型的稀土配合物Eu0.5Tb0.5(TTA)3Phen，并采用原位乳液聚合法进一步制备了Eu0.5Tb0.5(TTA)3Phen/PMMA稀土聚合物。利用红外光谱仪(IR)、电子探针X射线能谱仪等对其结构进行了表征，利用扫描隧道电子显微镜(SEM)、荧光光谱仪(FS)等研究了其微观形貌，并探讨了其发光性能。结果表明，聚合物中PMMA与稀土部分Eu0.5Tb0.5(TTA)3Phen通过键合的方式结合, 仍保持Eu0.5Tb0.5(TTA)3Phen原有的发光特性;在365 nm紫外光的激发下，产生发光峰在611.8 nm附近、谱线带宽为10.4 nm的红光发射，发光亮度高，色纯度高;Eu0.5Tb0.5(TTA)3Phen/PMMA具有良好的发光性能，其发光强度与MMA加入的含量有关。

| Abstract: | In the present paper,Eu0.5Tb0.5(TTA)3Phen was synthesized and Eu0.5Tb0.5(TTA)3Phen/PMMA was prepared by in-situ polymerization. The structure of Eu0.5Tb0.5(TTA)3Phen/PMMA was characterized by FTIR spectra. Microscopic morphology and photoluminescence properties were investigated by SEM photographs and fluorescence spectra. The results indicated that polymer parts were attached with the rare-earth molecular parts in the composite luminescent materials.And Eu0.5Tb0.5(TTA)3Phen/PMMA could emit mostly character... |
