Intensity-tunable micelles and films containing bimetal ions-europium(III) and terbium(III).

In this paper, multicolored micelles were prepared by coordination of lanthanide(III) (europium(III) (Eu(III)) and terbium(III) (Tb(III))) ions with block copolymer in different molar ratios of n/ n. The micelles formed by polymer-Eu(III)/Tb(III) could emit higher quantum yield luminescence than the mixture of polymer-Eu(III) micelles and polymer-Tb(III) micelles. The micelles containing Eu(III) and Tb(III) could emit a yellow-green color, and the intensity varied with the molar ratios of n/ n. In the constant concentrations of Eu(III) and 1,10-phenanthroline (Phen), the intensity of D→F increased with the addition of Tb(III), and the intensity of D→F decreased with the increasing of Eu(III) in the constant concentrations of Tb(III) and Phen. All the multicolored micelles could be spin-coated as intensity-tunable films. [ABSTRACT FROM AUTHOR]
