The synthetic approach results in the formation of a highly ordered lamellar nanocomposite consisting of yttrium or gadolinium oxide crystalline layers with a confined thickness of about 0.6 nm, separated from each other by organic layers of intercalated benzoate molecules. When the inorganic layers are doped with optically\u2010active lanthanide ions they show outstanding emission properties in the green (Tb<jats:sup>3+<\/jats:sup>), red (Eu<jats:sup>3+<\/jats:sup>) and near infrared (Nd<jats:sup>3+<\/jats:sup>). The local environment of the emitting ions and the energy transfer processes involving the phenyl ring of the benzoate complexes and the lanthanide ions are presented, as well as radiance and lifetime measurements. The radiance values are comparable and in some cases even larger than those of standard phosphors, proving that these nanohybrids can compete, from an emission efficiency point of view, with commercial phosphors. Furthermore, in these nanohybrids it is possible by simply changing the excitation wavelength, to tune the emission colour chromaticity without loosing the radiance.<\/jats:p>","DOI":"10.1002\/cphc.200600317","type":"journal-article","created":{"date-parts":[[2006,8,29]],"date-time":"2006-08-29T07:04:26Z","timestamp":1156835066000},"page":"2215-2222","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Optical Properties of Lanthanide\u2010Doped Lamellar Nanohybrids"],"prefix":"10.1002","volume":"7","author":[{"given":"Rute A.","family":"S\u00e1 Ferreira","sequence":"first","affiliation":[]},{"given":"Mohamed","family":"Karmaoui","sequence":"additional","affiliation":[]},{"given":"S\u00f3nia S.","family":"Nobre","sequence":"additional","affiliation":[]},{"given":"Lu\u00eds D.","family":"Carlos","sequence":"additional","affiliation":[]},{"given":"Nicola","family":"Pinna","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2006,10,2]]},"reference":[{"doi-asserted-by":"publisher","key":"e_1_2_6_1_2","DOI":"10.1039\/b509097k"},{"doi-asserted-by":"publisher","key":"e_1_2_6_2_2","DOI":"10.1002\/adma.200300389"},{"doi-asserted-by":"publisher","key":"e_1_2_6_3_2","DOI":"10.1038\/nmat1251"},{"doi-asserted-by":"publisher","key":"e_1_2_6_4_2","DOI":"10.1039\/b207789b"},{"doi-asserted-by":"publisher","key":"e_1_2_6_5_2","DOI":"10.1021\/ja057264b"},{"doi-asserted-by":"publisher","key":"e_1_2_6_6_2","DOI":"10.1021\/ja993280v"},{"doi-asserted-by":"publisher","key":"e_1_2_6_7_2","DOI":"10.1021\/cm049945w"},{"doi-asserted-by":"publisher","key":"e_1_2_6_8_2","DOI":"10.1021\/ja026501x"},{"doi-asserted-by":"publisher","key":"e_1_2_6_9_2","DOI":"10.1021\/jp027533"},{"doi-asserted-by":"publisher","key":"e_1_2_6_10_2","DOI":"10.1021\/ja983361b"},{"doi-asserted-by":"publisher","key":"e_1_2_6_11_2","DOI":"10.1021\/ja027115i"},{"doi-asserted-by":"publisher","key":"e_1_2_6_12_2","DOI":"10.1021\/cm021203k"},{"doi-asserted-by":"publisher","key":"e_1_2_6_13_2","DOI":"10.1021\/ja0494959"},{"doi-asserted-by":"publisher","key":"e_1_2_6_14_2","DOI":"10.1002\/ange.200353300"},{"doi-asserted-by":"publisher","key":"e_1_2_6_14_3","DOI":"10.1002\/anie.200353300"},{"doi-asserted-by":"publisher","key":"e_1_2_6_15_2","DOI":"10.1016\/j.colsurfa.2004.04.078"},{"doi-asserted-by":"publisher","key":"e_1_2_6_16_2","DOI":"10.1002\/adma.200400460"},{"doi-asserted-by":"publisher","key":"e_1_2_6_17_2","DOI":"10.1002\/ange.200460610"},{"doi-asserted-by":"publisher","key":"e_1_2_6_17_3","DOI":"10.1002\/anie.200460610"},{"doi-asserted-by":"publisher","key":"e_1_2_6_18_2","DOI":"10.1021\/cm050060"},{"doi-asserted-by":"publisher","key":"e_1_2_6_19_2","DOI":"10.1021\/ja042323r"},{"doi-asserted-by":"publisher","key":"e_1_2_6_20_2","DOI":"10.1002\/smll.200400014"},{"unstructured":"M.
