| 1 | Red, green and blue aggregation-induced emissive carbon dots显示文摘As one of the most promising fluorescent nanomaterials, carbon dots(CDs) have been extensively studied for their fluorescent properties in solution. However, research on the synthesis of multicolor solid-state fluorescence(SSF) CDs(from blue to red) is rarely reported. Herein, we used o-phenylenediamine, mphenylenediamine and p-phenylenediamine with dithiosalicylic acid(DTSA) in the solvothermal reaction using acetic acid as a solvent to obtain aggregation-induced emissive(AIE) CDs of red(620 nm), green(520 nm), and blue(478 nm), respectively. XPS spectra and TEM image show that with the red-shift of luminescence, the particle size and content of C=O of the CDs gradually increases. Finally, based on the non-matrix solid-state multicolor luminescence characteristics of CDs, the application of white light LED devices is realized. Besides, based on the fat-soluble properties of CDs, fingerprint detection applications are realized. | Xiaokai Xu Luoqi Mo Wei Li Yadong Li Bingfu Lei Xuejie Zhang Jianle Zhuang Chaofan Hu Yingliang Liu | 2021 | Chinese Chemical Letters2021，32，12： | 0 |
