biostudies-literatureUnknown9(3)Wang XIn this research contribution, nano-aggregates have been fabricated by introducing lanthanide (Ln3+) ions into solutions of amphiphilic diblock copolymers of polystyrene-b-poly (acrylic acid) (PS-b-PAA). The coordination of acrylic acid segments to lanthanide cations induces diblock copolymer (BCPs) self-assembly in order to design stable white luminescent hybrid nanoparticles with fine uniform particle size. The introduction of Ln3+ ions (Eu3+ and Tb3+) bestows the micelles, precisely white light, upon excitation of 342 nm. Lanthanide coordination cross-linking of poly (acrylic acid) segments, or blocks, endows the micelles higher thermal stability than that of BCPs micelles without cross-linking. As the most important key point of this work, the regular and stable nano-particles with high emission quality can make fully flexible electroluminescent devices with self-formation or uncoordinated into polymer hosts. Instead of inorganic luminescent nanoparticles with hard cores, this method can potentially apply for fully flexible white-light emitting diodes (FFWLEDs).Nanomaterials (Basel, Switzerland)E363https://www.ebi.ac.uk/biostudies/studies/S-EPMC6474134biostudies-literatureLn3+-Induced Diblock Copolymeric Aggregates for Fully Flexible Tunable White-Light Materials.PMC6474134Tang JDing WRen JZhang XWang GWang WWang XHuang LWang YBelfiore LAShen WfalseLn3+-Induced Diblock Copolymeric Aggregates for Fully Flexible Tunable White-Light Materials.In this research contribution, nano-aggregates have been fabricated by introducing lanthanide (Ln3+) ions into solutions of amphiphilic diblock copolymers of polystyrene-b-poly (acrylic acid) (PS-b-PAA).
