Polarized ff-Emission of Terbium(III)by using the Stretched Polymer Film Technique

摘要

A Novel coordination system with ff-emission of Tb(III)was obtained on a polyvinyl alcohol(PVA)film surface.On this film the ff-emission is polarized,and is intensified by polymer stretching.XAFS spectra show that the mean bond distances between Tb(III)and the nearest neighbour atoms of the 1,10,-phenanthroline ligand on the film are close to those in[Tb(SA)3],Tb(NO3)3H2O and[Tb(phen)2(NO3)3].
