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。
The copolymerization of various rare earth europium complexes with styrene (ST) / methacrylic acid (HMA) was reported. The optical properties of transparent optical resins containing rare earth complexes were investigated. It is found that it has the characteristics of high luminescence efficiency, sharp linear spectrum of the spectrum and red shift of the emission of the optical resin doped with the rare earth complex relative to the pure rare earth complex powder. In particular, the optical resin emission spectra of rare earth-doped complexes are explained by the electron cloud rearrangement effect (a slight shift of the transition band positions between the same J-energy levels when the central rare earth ions are bound to different ligands) Redshift phenomenon, and deduced that the rare earth complexes with the optical resin, the rare earth central ion and the distance between the coordination atoms decreased.
