We utilize the dopant-matrix strategy and emulsion polymerization to obtain aqueous afterglow dispersions from a liquid precursor, which avoids the processing of solid materials, protects organic triplets and achieves long phosphorescence lifetime of 7.64 s. The aqueous afterglow dispersions display great potential for biomedical applications due to their ultralong-lived excited states.
我们采用掺杂剂-基质策略和乳液聚合方法，从液体前驱体制备水性余辉分散体，这避免了固体材料的加工，保护了有机三线态，并实现了7.64秒的长磷光寿命。由于其超长寿命的激发态，水性余辉分散体在生物医学应用中显示出巨大潜力。
