The Luminescence of Rare Earth Composite Micelles in Different Polarity

Abstract:

The luminescence of rare earth composite micelles was measured in different polarity. The polarity of complexes was changed with the molar ratios of block copolymers, trivalent europium (Eu (III)) ions and 1,10-phenanthroline (Phen). When 4-vinyl pyridine (4VP) coordinated with central ions Eu (III), the improved asymmetry of composite micelles resulted in higher polarity. The higher polarity strengthened the ability of electron transition, which improved the luminescence of complexes. When Phen participated in coordination, the polarity was improved further. The strongest luminescence of complexes could be obtained by changing the molar ratios of block copolymers, Eu (III) ions and Phen.
