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.<\/jats:p>","DOI":"10.3390\/polym10050508","type":"journal-article","created":{"date-parts":[[2018,5,8]],"date-time":"2018-05-08T02:48:08Z","timestamp":1525747688000},"page":"508","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["The Coordination and Luminescence of the Eu(III) Complexes with the Polymers (PMMA, PVP)"],"prefix":"10.3390","volume":"10","author":[{"given":"Weican","family":"Zhao","sequence":"first","affiliation":[{"name":"School of Chemistry and Materials Science, Heilongjiang University, Harbin 150086, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haifeng","family":"Shao","sequence":"additional","affiliation":[{"name":"School of Chemistry and Materials Science, Heilongjiang University, Harbin 150086, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guang","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Chemistry and Materials Science, Heilongjiang University, Harbin 150086, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3077-670X","authenticated-orcid":false,"given":"Yanjun","family":"Hou","sequence":"additional","affiliation":[{"name":"School of Chemistry and Materials Science, Heilongjiang University, Harbin 150086, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuhong","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Functional Inorganic Material Chemistry, Heilongjiang University, Harbin 150086, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,5,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"509","DOI":"10.1002\/adma.200801635","article-title":"Lanthanide-containing light-emitting organic-inorganic hybrids: A bet on the future","volume":"40","author":"Carlos","year":"2009","journal-title":"Adv.
