| 2 | Near-infrared emissive carbon dots with 33.96% emission in aqueous solution for cellular sensing and light-emitting diodes显示文摘Near-infrared emissive carbon dots(CDs) were synthesized by hydrothermal method. The as-prepared CDs exhibited a relatively high quantum yield(QY) of 33.96% in an aqueous solution, and the peak toward the near-infrared fluorescence reached 685 nm. The CDs exhibited pH-sensitive characteristics under strong acidic conditions. Even at pH = 0, the as-prepared CDs retained a high fluorescence intensity,which proved that they possessed good acid resistance. More importantly, the CDs were sensitive to the Fe3+changes in living cells. In addition, they could also be used for white and red emissive LEDs.This discovery will expand the use of aqueous-phase high QY CDs in the field of living cell sensing and imaging. | Boyang Wang Jian Li Zhiyong Tang Bai Yang Siyu Lu | 2019 | Science Bulletin2019，64，17： | 9 |
| 3 | High production-yield solid-state carbon dots with tunable photoluminescence for white/multi-color light-emitting diodes显示文摘Plastic waste is generally resistant to natural degradation and has become a major environmental pollution problem globally. The pollution of ecosystems seriously affects the health and survival of organisms,including humans. Much attention has been paid to finding suitable ways to convert plastic waste into high-value-added carbon materials. To this end, we report the high production yield(60%–85%) of carbon dots(CDs) for solid-state fluorescence(SSF) obtained by a one-step solvothermal method using waste expanded polystyrene as the precursor. The SSF mechanism of the CDs was also explored. Their emission wavelength, with a large full width at half maximum of 150–200 nm, exhibited tunable photoluminescence from white to yellow and orange. CDs powder was used to fabricate single-component white and multi-colour light-emitting diodes on UV chips. Overall, plastic waste was converted into tunable solid-state fluorescent CDs powder, which has promising applications in carbon-based lighting, by a simple solvothermal method that provides a viable method for recycling plastic waste. | Haoqiang Song Xuejian Liu Boyang Wang Zhiyong Tang Siyu Lu | 2019 | Science Bulletin2019，64，23： | 6 |
| 4 | Ethanol-derived white emissive carbon dots:The formation process investigation and multi-color/white LEDs preparation显示文摘Carbon dots(CDs)have attracted much attention due to their excellent photoelectric properties and potential applications.Although previous studies have shown that almost all organic molecules can be converted into CDs via chemical carbonization,the mechanism of the conversion process remains unclear.The hydrothermal/solvothermal method commonly used to prepare CDs is complicated and leads to the generation of many by-product CDs with similar structures.Considering that the purification of the synthesized by-products is difficult,the process of CDs formation cannot be readily analyzed and understood.Herein,we use ethanol as a carbon source to synthesize white-emitting CDs(W-CDs).Column chromatography separation shows that the synthesized W-CDs are composed of blue-,cyan-,and yellow-emitting CDs that fluoresce at wavelengths corresponding to the three emission centers of W-CDs.Although the samples have similar graphitic structure,they exhibit different surface states due to variations in the degree of oxidation and carbonization.Therefore,the red-shift in their emission peaks is attributed to an increased degree of carbonization in their polymer structure.Theoretical calculations verify the experimental results,and the prepared CDs are successfully used to develop multi-color and white light-emitting diodes(LEDs). | Boyang Wang Haoqiang Song Zhiyong Tang Bai Yang Siyu Lu | 2022 | Nano Research2022，15，2： | 5 |

| 6 | Red-emitting,self-oxidizing carbon dots for the preparation of white LEDs with super-high color rendering index显示文摘Carbon dots(CDs),as a kind of carbon nanomaterials,have attracted widespread attention due to their unique structure and excellent optical properties,and they are low-cost,environmentally friendly and biocompatible.However,the development of near-infrared(NIR)emission CDs remains a challenge.In this study,we successfully prepared CDs with a maximum emission of714 nm using citric acid as the carbon source,thiourea and ammonium fluoride as the dopant source,and N,N-dimethylformamide as the solvent.The quantum yield(QY)is as high as 22.64%.Interestingly,the prepared CDs self-oxidize in the presence of oxygen,resulting in a blue shift of their emission.Therefore,they can be used to prepare white light-emitting diodes(WLEDs)without adding other fluorescent substances.Notably,the work presented herein constitutes the first report of WLEDs preparation from single CDs. | Xin Yang Laizhi Sui Boyang Wang Yongqiang Zhang Zhiyong Tang Bai Yang Siyu Lu | 2021 | Science China Chemistry2021，64，9： | 1 |
| 7 | Ruscogenin alleviates LPS-triggered pulmonary endothelial barrier dysfunction through targeting NMMHC IIA to modulate TLR4signaling显示文摘Pulmonary endothelial barrier dysfunction is a hallmark of clinical pulmonary edema and contributes to the development of acute lung injury(ALI).Here we reported that ruscogenin(RUS),an effective steroidal sapogenin of Radix Ophiopogon japonicus,attenuated lipopolysaccharides(LPS)-induced pulmonary endothelial barrier disruption through mediating non-muscle myosin heavy chain IIA(NMMHC IIA)-Toll-like receptor 4(TLR4)interactions.By in vivo and in vitro experiments,we observed that RUS administration significantly ameliorated LPS-triggered pulmonary endothelial barrier dysfunction and ALI.Moreover,we identified that RUS directly targeted NMMHC IIA on its N-terminal and head domain by serial affinity chromatography,molecular docking,biolayer interferometry,and microscale thermophoresis analyses.Downregulation of endothelial NMMHC IIA expression in vivo and in vitro abolished the protective effect of RUS.It was also observed that NMMHC IIA was dissociated from TLR4 and then activating TLR4 downstream Src/vascular endothelial cadherin(VE-cadherin)signaling in pulmonary vascular endothelial cells after LPS treatment,which could be restored by RUS.Collectively,these findings provide pharmacological evidence showing that RUS attenuates LPS-induced pulmonary endothelial barrier dysfunction by inhibiting TLR4/Src/VE-cadherin pathway through targeting NMMHC IIA and mediating NMMHC IIA-TLR4 interactions. | Yunhao Wu Xiu Yu Yuwei Wang Yalin Huang Jiahui Tang Shuaishuai Gong Siyu Jiang Yuanli Xia Fang Li Boyang Yu Yuanyuan Zhang Junping Kou | 2022 | Acta Pharmaceutica Sinica B2022，12，3： | 0 |
