CPL spectrum measurement of europium complex Eu(facam)3 exhibiting a sharp fluorescence spectrum

Circularly Polarized Luminescence (CPL) measures the difference of intensity between right-handed and left-handed circular polarized fluorescence light. Luminescent molecules which generate CPL may find technological applications in the field of 3D displays and security markers. Chiral lanthanide complexes have been extensively applied in this field, while exhibiting sharp fluorescent bands and requiring, in CPL spectrum measurement, the use of narrow bandwidth. Two monochromators are installed in CPL-300, one is in the excitation side, and the other is in emission side, both equipped with continuously variable slits, in order to select the appropriate excitation wavelength and a suitable fluorescence bandwidth. So the CPL-300 can measure the sample which shows sharp CPL spectrum with high resolution.

In this application note, the high resolution CPL spectrum measurement of europium tris 3- (trifluoromethylhydroxymethylene)-(+)-camphorate (Eu(facam)3 (trifluoromethylhydroxymethylene) (+) camphorate] (Eu(facam) )/DMSO solution using CPL-300 is 3)/DMSO solution using CPL 300 is presented.
