The ligands employed in this work were poly(sodium acrylate), working as polymeric matrix, and 1,10-phenanthroline, taking advantage of its antenna effect. Possibilities of color display were further enhanced by incorporating a cationic polyfluorene with blue emission. This strategy allowed for obtaining cyan and magenta, besides the aforementioned colors. Uncoated cellulose paper was impregnated with the resulting luminescent inks, observing a strong hypsochromic shift in excitation wavelength upon drying. Hence, while a cheap UV-A lamp sufficed to reveal the polyfluorene\u2019s blue emission, shorter wavelengths were necessary to visualize the emission due to lanthanide ions as well. The capacity to reveal, with UV-C radiation, a full-color image that remains invisible under natural light is undoubtedly useful for anti-counterfeiting applications. Furthermore, both lanthanide ion complexes and polyfluorenes were shown to have their luminescence quenched by Cu(II) ions and nitroarenes, respectively.<\/jats:p>","DOI":"10.3390\/molecules28166164","type":"journal-article","created":{"date-parts":[[2023,8,21]],"date-time":"2023-08-21T09:07:16Z","timestamp":1692608836000},"page":"6164","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Luminescent Papers with Asymmetric Complexes of Eu(III) and Tb(III) in Polymeric Matrices and Suggested Combinations for Color Tuning"],"prefix":"10.3390","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9864-1794","authenticated-orcid":false,"given":"Roberto J.","family":"Aguado","sequence":"first","affiliation":[{"name":"LEPAMAP-PRODIS Research Group, University of Girona, Maria Aur\u00e8lia Capmany 61, 17003 Girona, Spain"}]},{"given":"Beatriz O.","family":"Gomes","sequence":"additional","affiliation":[{"name":"University of Coimbra, CQC, Department of Chemistry, Rua Larga, 3004-535 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3336-2449","authenticated-orcid":false,"given":"Luisa","family":"Dur\u00e3es","sequence":"additional","affiliation":[{"name":"University of Coimbra, CIEPQPF, Department of Chemical Engineering, Rua S\u00edlvio Lima, 3030-790 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4612-7686","authenticated-orcid":false,"given":"Artur J.
