“…Lanthanide ions are widely used in the field of optical and magnetic researches on the basis of their peculiar luminescent and magnetic properties [1,2,3,4,5,6]. However, Ln(III) ions are unable to show a high luminous emission under direct excitation because the f–f transitions of lanthanide ions are spin-forbidden.…”

The rare earth complexes and the polymers can be made into composite nanofibers through electrospinning. The fluorescence intensity of these fiber composites is much higher than that of the rare earth complexes. By changing the mixed proportion of polymethyl methacrylate (PMMA) and complexes, nanofiber materials were prepared. Then, by measuring their fluorescence intensity, it is found that the carbonyl bond of PMMA may have coordinated with the rare earth ions and enhanced the luminescence intensity of them. Then, a series of experiments were designed to study their coordination and luminescence mechanism. The coordination mechanism of the polymers with carbonyl groups and the rare earth complexes was explained by Eu(TFT)3(TPPO), Eu(TFT)3(TPPO)2, Eu(PFP)3(TPPO), Eu(PFP)3(TPPO)2, and polyvinyl pyrrolidone (PVP) dissolved in chloroform solution, where TFT means 2-(2,2,2-trifluoroethyl)-1-tetralone, PFP means 2-(2,2,3,3,3-Pentafluoropro-panoyl)-3,4-dihydronaphthalen-1(2H)-one and TPPO means phosphine oxide. The coordination of PVP and the rare earth complexes in solution was studied, and it was found that the fluorine atoms of the ligand had a significant impact on the aggregation-induced effect of the composites. The electron transitioned in the polymers and the complexes were enhanced greatly by the coordination. The colors of emission light could be adjusted by the coordination of the polymers and the rare earth complexes.

“…The Ln 3+ -activated luminescent materials (Ln = Eu, Tb, or Ce, and so on) have been acquired and applied successfully by many methods [5][6][7][8][9][10]. However, excited bands of most these luminescence materials are at about 254 nm and the single emission of Eu 3+ -activated luminescent materials originated from 4f-4f transitions show sharp emission peaks because of the sensitivity of lanthanide ions for their chemical environments [11].…”

“…Zeolites are one of the promising host materials for photonic applications in blue, green, red or white phosphors for ultraviolet light-emitting diodes (LEDs) [12,13]. Through exchanging lanthanide and zeolite 13X, lanthanide ions can be protected and multicolored luminescence can be observed because of their well-ordered arrangement of cages and channels [10].…”
