| 摘 要： | 报道了将多种稀土铕配合物复合于苯乙烯(ST)／甲基丙烯酸(HMA)的共聚体系,研究了含稀土配合物透明光学树脂的光学性能。发现其具有发光效率高,光谱呈现尖锐的线状谱带及相对于纯稀土配合物粉末来说掺有稀土配合物的光学树脂的发射产生光谱红移等特点。特别是用电子云重排效应(当中心稀土离子与不同配体结合时,其相同的J能级间的跃迁谱带位置略有移动的现象)解释了掺有稀土配合物的光学树脂发射光谱红移现象。并推断出在含稀土配合物复合于光学树脂后。稀土中心离子和配位原子间距离有所减小。

| Abstract: | This paper reports some optical properties of the optical resins St/HMA containing rare earth complexes, such as high fluorescent intensity, longer luminescent lifetime, sharp spectral lines and red shift of the emission spectra. Especially it explained the cause of red shift that the emission spectra of the optical resin containing the rare earth complex compared to that of the rare earth complex powder using Nephelauxetic effect theory. When the rare earth complexes were incorporated into the optical resins, the transparent optical resins "freeze" the vibrations and rotations of the organic ligand molecules, this makes the distance between trivalent rare earth ion and coordination atoms decreased. |
