摘　　要：三重态-三重态湮灭(TTA)上转换是一种通过多光子机制将低能量光波向高能量光波转换的技术,在太阳能电池、光催化、生物成像、防伪等领域具有潜在的应用前景。传统的TTA上转换一般在无氧溶液中发生,使得其应用领域严重受限。近几年固态TTA上转换发光材料的发展引起了研究者的关注,该文从TTA上转换体系聚合物基质的状态以及TTA体系在聚合物中的分散形式出发,总结了近十年TTA上转换体系在聚合物基质中的研究进展。Triplet-triplet annihilation(TTA)upconversion is a technique converting low-energy photos into high-energy photos by a multi-photon mechanism.The TTA based upconversion has a broad application prospect in solar cells,photocatalytic,anti-counterfeiting and bioimaging,etc.The traditional TTA-based upconversion mainly occurs in anaerobic solution,which may significantly limit its applications.Recently,the development of TTA upconversion in solid state has attracted much attention.And the development over the past ten years of solid-state TTA upconversion in polymer matrix from the state of polymer and the dispersion mode of TTA system is summarized in this review.
