Stabilization of dye-sensitized upconversion luminescence by a combined suppressing–scavenging strategy
Yuxia Luo, Huan Xing, Yuxi Liu, Chaohao Chen, Lijun Jiang, Hao Ma, Zemin He, Xinping Li, Guochen BaoA dual-stabilization strategy combining triplet-state quenching and singlet-oxygen scavenging overcomes poor photostability in dye-sensitized UCNPs, achieving a 114 min luminescence half-life under low-power LED excitation.
