While luminescence from organic dyes has previously been described in the structurally closely related montmorillonites, attempts to obtain luminescence from occluded rare earths is not known to exhibit significant efficiency. This may in part be due to the presence of significant amounts of iron, but is mostly due to the inherent presence of water and structural OH groups. In the present paper, attempts to screen Tb3+ from disadvantageous matrix interactions by generating complexes with 2,2'-bypyridine within the interlayers are described, which eventually yield a 12-fold increase in emission intensity on complexation or about 20% in quantum efficiency, respectively. Even very low levels of iron impurities appear to still be a delimiting factor with regard to optical efficiency. However, if these can be avoided, the distinctly two-dimensional morphological features of of the hectorites or other clay minerals may be exploited toward new interesting optical applications. 000057169 536__ $$0G:(DE-Juel1)FUEK407$$2G:(DE-HGF)$$aTerrestrische Umwelt$$cP24$$x0 000057169 588__ $$aDataset connected to Web of Science 000057169 650_7 $$2WoSType$$aJ 000057169 7001_ $$0P:(DE-HGF)0$$aBenevante, E.$$b1 000057169 7001_ $$0P:(DE-HGF)0$$aBentlage, M.$$b2 000057169 7001_ $$0P:(DE-HGF)0$$aEchevarría, Y.$$b3 000057169 7001_ $$0P:(DE-Juel1)129484$$aKlumpp, E.$$b4$$uFZJ 000057169 7001_ $$0P:(DE-HGF)0$$aKynast, U.$$b5 000057169 773__ $$0PERI:(DE-600)1500399-1$$a10.1021/cm061031h$$gVol. 19, p. 1098 - 1102$$p1098 - 1102$$q19<1098 - 1102$$tChemistry of materials$$v19$$x0897-4756$$y2007 000057169 8567_ $$uhttp://dx.doi.org/10.1021/cm061031h 000057169 909CO $$ooai:juser.fz-juelich.de:57169$$pVDB 000057169 9131_ $$0G:(DE-Juel1)FUEK407$$bErde und Umwelt$$kP24$$lTerrestrische Umwelt$$vTerrestrische Umwelt$$x0 000057169 9141_ $$y2007 000057169 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000057169 9201_ $$0I:(DE-Juel1)VDB793$$d31.10.2010$$gICG$$kICG-4$$lAgrosphäre$$x1 000057169 970__ $$aVDB:(DE-Juel1)89922 000057169 980__ $$aVDB 000057169 980__ $$aConvertedRecord 000057169 980__ $$ajournal 000057169 980__ $$aI:(DE-Juel1)IBG-3-20101118 000057169 980__ $$aUNRESTRICTED 000057169 981__ $$aI:(DE-Juel1)IBG-3-20101118
