Journal ArticleDOI
Near-infrared-triggered photon upconversion tuning in all-inorganic cesium lead halide perovskite quantum dots.
Wei Zheng,Ping Huang,Zhong-Liang Gong,Datao Tu,Jin Xu,Qilin Zou,Renfu Li,Wenwu You,Jean-Claude G. Bünzli,Xueyuan Chen +9 more
TL;DR: The authors drive high-efficiency, tunable upconversion luminescence in perovskite quantum dots by energy transfer from lanthanide-doped nanoparticles excited by near-infrared light, to produce full-color emission with low driving power.
Journal ArticleDOI
Controlled Synthesis of Ag2S Quantum Dots and Experimental Determination of the Exciton Bohr Radius
TL;DR: In this article, the size-dependent excited state optical properties of Ag2S QDs are systematically investigated by photoluminescence (PL), PL excitation (PLE), and time-resolved PL spectroscopy.
Journal ArticleDOI
Sub-10 nm lanthanide-doped CaF2 nanoprobes for time-resolved luminescent biodetection.
Wei Zheng,Shanyong Zhou,Zhuo Chen,Ping Hu,Yongsheng Liu,Datao Tu,Haomiao Zhu,Renfu Li,Mingdong Huang,Xueyuan Chen +9 more
TL;DR: Lanthanide-doped luminescent nanoparticles have provoked considerable interest due to their superior features, such as sharp f–f emission peaks, a long photoluminescence lifetime, low toxicity, and high resistance to photo-bleaching.
Journal ArticleDOI
Lanthanide-doped luminescent nano-bioprobes: from fundamentals to biodetection
TL;DR: A brief overview of the most recent advances in Ln(3+)-doped luminescent inorganic NPs as sensors is provided, which covers from their chemical and physical fundamentals to biodetection, such as controlled synthesis methodology, surface modification chemistry, optical physics, and their promising applications in diverse bioassays.
Journal ArticleDOI
Broadband Extrinsic Self-Trapped Exciton Emission in Sn-Doped 2D Lead-Halide Perovskites
Jiancan Yu,Jintao Kong,Wei Hao,Xintong Guo,Huajun He,Wan Ru Leow,Zhiyuan Liu,Pingqiang Cai,Guodong Qian,Shuzhou Li,Xueyuan Chen,Xiaodong Chen +11 more
TL;DR: Sn-triggered extrinsic self-trapping of excitons in bulk 2D perovskite crystal, PEA2 PbI4 (PEA = phenylethylammonium), is reported, where exciton self-Trapping never occurs in its pure state.
