A Self-Quenching-Resistant Carbon-Dot Powder with Tunable Solid-State Fluorescence and Construction of Dual-Fluorescence Morphologies for White Light-Emission.
Yonghao Chen,Mingtao Zheng,Yong Xiao,Hanwu Dong,Haoran Zhang,Jianle Zhuang,Hang Hu,Bingfu Lei,Yingliang Liu +8 more
TL;DR: Self-quenching in the aggregation state is overcome, and tunable solid-state photoluminescence of carbon-dot powder is achieved, and a novel concept, i.e., constructing dual-fluorescence morphologies from single luminescent species, is presented to realize white-light emission.

Solid‐State Carbon Dots with Red Fluorescence and Efficient Construction of Dual‐Fluorescence Morphologies
Jiangling He,Youling He,Yonghao Chen,Bingfu Lei,Jianle Zhuang,Yong Xiao,Yeru Liang,Mingtao Zheng,Haoran Zhang,Yingliang Liu +9 more
TL;DR: Stable solid-state red fluorescence from organosilane-functionalized carbon dots (CDs) with sizes around 3 nm is reported for the first time and a novel method for the efficient construction of dual-fluorescence morphologies is first reported.

Construction and multifunctional applications of carbon dots/PVA nanofibers with phosphorescence and thermally activated delayed fluorescence
Jiangling He,Youling He,Yonghao Chen,Xuejie Zhang,Chaofan Hu,Jianle Zhuang,Bingfu Lei,Yingliang Liu +7 more
TL;DR: In this paper, an ordered mesoporous structure from the electrospun CDs/PVA nanofibers can effectively stabilize the triplet states of CDs, thus enabling the reverse intersystem crossing (RISC) process for TADF and realizing the first example in CDs/polymer system.

Room temperature phosphorescence from moisture-resistant and oxygen-barred carbon dot aggregates
TL;DR: In this article, aggregation-induced room temperature phosphorescence (RTP) is first reported in self-quenching-resistant nitrogen-doped carbon dot powder, which is suggested to take advantage of the moisture-resistance, rigidization and oxygen-barrier induced by PVA-chains.

Anchoring Carbon Nanodots onto Nanosilica for Phosphorescence Enhancement and Delayed Fluorescence Nascence in Solid and Liquid States
Jiangling He,Yonghao Chen,Youling He,Xiaokai Xu,Bingfu Lei,Haoran Zhang,Jianle Zhuang,Chaofan Hu,Yingliang Liu +8 more
TL;DR: Electron trap can capture, store, and gradually release the electrons just like an electron transporter to improve the intersystem crossing and reserved ISC, having provided the more stabilized triplet excitons, stronger and longer phosphorescence, and also triggered the formation of thermally activated delayed fluorescence (TADF), offering a new mechanism for exploiting LLE among CD-based field.
