Properties of Europium (III) Chelating Polymer Film

A europium (III) chelating polymer film has been investigated by fluorescence spectrum, lifetime measurement, near-field scanning optical microscopy (NSOM) and m-line method. The obtained film thickness is 1.748μm and refractive index is 1.571. Near-field scanning optical microscopy shows the good surface quality of the Europium (III) chelating polymer film.
