Modified photoluminescence properties of rare-earth complex/polymer composite fibers prepared by electrospinning

Ribbon-like microfibers of a new composite of europium complex Eu(aspirin)3(Phen) (aspirin is acetylsalicylic acid; Phen represents 1,10-phenanthroline) and polystyrene (PS) were prepared successfully by electrospinning with different mass ratios of Eu(aspirin)3(Phen) complex to PS = 1:10, 1:40 and 1:160. The microfibers were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and fluorescence spectrophotometry. It was found that the fibers displayed excellent photoluminescence properties compared with rare-earth complex. The photoluminescence intensity and the emission intensity of the peak at 616 nm (5D0→7F2) of Eu-ions increased with the Eu(aspirin)3(Phen) loading. No obvious fluorescence quenching was observed. Further discussion on the structural and optical properties of the microribbons was presented. This kind of materials might be expected to be applied for optical or optoelectronic devices.

The Rare Earth

A UV-cured composite containing a rare earth complex was prepared for this study. First, the photoluminescent terbium complex was synthesized with a long-chain unsaturated fatty acid (10-Undecenoic acid) by a solution precipitation method, resulting in the 10-UA-Tb(III) complex. Its structure was proven by FTIR, elemental analysis, XRD, and TGA. The results indicated that the organic acid ligand successfully coordinated with the Tb3+ ion and that the complex had a chelate bidentate structure. The emission spectrum of the 10-UA-Tb(III) complex indicated that the complex can emit a bright green light with the unique luminescence of the Tb3+ ion. Furthermore, the luminescence properties of complexes with different ratios of Tb3+ and ligand were studied, and the ratio of Tb3+ and the ligand had an obvious impact on the luminescence intensity of the 10-UA-Tb(III) complex. Subsequently, the prepared rare earth complex was doped into a UV-cured coating in different proportions to obtain a UV-cured composite. The morphology of the rare earth UV-cured composite was observed by SEM. The images showed that the rare earth complex was dispersed uniformly in the polymer matrix. Moreover, the composites could emit fluorescence. Additionally, it has good thermal stability and compatibility with the resin. Therefore, these composites should have potential applications in UV curable materials, such as luminescence coatings.
