Effect of varying lanthanide local coordination sphere on luminescence properties illustrated by selected inorganic and organic rare earth complexes synthesized in sol–gel host glasses

Silver nanoparticles-enhanced rare earth co-luminescence effect of Tb(III)–Y(III)–dopamine system

“…Decrease in the non-radiation thermal deactivation is mainly caused by hydroxyl vibration of water molecule around Ln 3 þ [41]. In this work, the fluorescence intensity was enhanced markedly by adding AgNPs into the Tb 3 þ -Y 3 þ -DA system.…”

Luminescent micro- and nanofibers based on novel europium phthalate complex

“…Thus, excitation lines attributed to 7 F 1 / 5 D J (J ¼ 4, 2) and 7 F 1 / 5 L 6 may be observed in the excitation spectrum, with their assignments and wavelengths presented in Table 3. The component centred at 386 nm could be also accounted as arising from the 7 F 1 / 5 L 7 transition [34].…”

“…Also, lanthanides doped hybrid inorganic-organic materials exhibit interesting luminescent properties [31,32]. Among those, the Eu 3þ doped hybrid materials were the subject of several papers that studied their emissive behaviors [33,34].…”

Investigation of the Chemistry for the Host Sol‐Gel Glass via the Energy Transfer Fluorescence of Encapsulated Organic‐Tb(III) Complexes

“…The de‐excitation results from a weak vibronic coupling of the rare earth ion excited state with high O–H oscillators. Non‐radiative deexcitation through O–H oscillations decreases the rare earth luminescence . The emission efficiency of these complexes largely depends on the choice of the organic ligand .…”
