Emission spectra of the sol–gel glass doped with europium(III) complexes of picolinic acid N-oxide—A new UV-light sensor

Stimuli-responsive europium-containing metallo-supramolecular polymers

“…These bands have been identified as the 5 D 0 / 7 F 0-3 transitions. 24 Upon increasing the concentration of Eu 3+ within the films there is a decrease in the emission band at 410 nm and the distinctive Eu 3+ -based emission bands at 590 nm and 615 nm appear.…”

“…Especially, lanthanide metal complexes have been extensively studied due to their unique luminescence properties (Lis et al, 2009;Godlewska et al, 2008;Legendziewicz, 2002). As an extension of our work (Kang, 2010;Oh et al, 2010;Kim et al, 2010;Seo et al, 2009) on luminescent complexes, herein, we report the crystal structure and luminescent properties of the title Tb(III) chloride complex with 3-methylpyridine-2-carboxylic acid (3-methylpicolinic acid), (I).…”

“…For general background to luminescent compounds, see: Fan et al (2009); Oh et al (2010); Seo et al (2010); Zhou et al (2010). For luminescence properties of metal compounds, see: Godlewska et al (2008); Kang (2010); Kim et al (2010); Legendziewicz (2002); Lis et al (2009); Seo et al (2009).…”

“…Metal complexes of picolinic acid and their derivatives have been of considerable interest due to their adoption of various coordination modes and their interesting photophysical properties (Seo et al, 2010;Kukovec et al, 2009;Hong et al, 2008;Soares-Santos et al, 2006). Especially, Eu(III) complexes have been extensively studied due to their unique luminescence properties such as narrow emission bands and the excitation spectra of the five-dimensional 0 -> 7F 0 transition (Lis et al, 2009;Godlewska et al, 2008;Legendziewicz et al, 2002). In this study, we report the synthesis and characterization of a Eu(III)-picolinic acid derivative in order to develop new lanthanide complexes for novel photoluminescent applications.…”
