As one of the hot spots in the international research field, the multi-dimensioned carbon nano-materials possesses numerous unique performances. Recently, Professor Chen Su of State Key Lab of Materials-Oriented Chemical Engineering and the College of Chemistry and Chemical Engineering and his research team members produced zero-dimension fluorescent carbon nano-materials(carbon quantum dots) with ordinary cheap eggs as raw material by plasm treatment. Their research achievement has been published in Angewandte Chemie International, which is an international authoritative journal in chemical field.
Carbon quantum dot is the newest member of carbon nano-materials family. Because of its distinguished advantages such as fluorescence performance and biocompatibility, Carbon quantum dot is favored by researchers gradually. In the research, they firstly treated the natural and nontoxic eggs by low temperature plasma for the purpose of obtaining the fluorescent carbon quantum dots in 3 minutes and giving good amphiphilicity. Through chemical analysis and real-time observation to the pyrolysis pocess of the samples, the formation mechanism of carbon quantum dot is introduced and expounded, providing new way of thinking in revealing the mechanism of its the photo physical behaviors. In the meantime, the carbon quantum dot is firstly used as fluorescent carbon ink, successfully accomplishing fluorescence patterning with inkjet printing and silk-screen printing. This hopefully can be applied in photoelectric device, biomarker and other fields. The research improved cognitive level of carbon quantum dot and expanded the preparation method of zero-demension carbon nano-material and its application. Based synthetically on the papers published in J. Am. Chem. Soc. 2011, 133 (22), 8412-8415; Angew. Chem. Int. Ed. 2011, 50 (16), 3706-3709; Adv. Mat. 2011, 23 (26), 2915-2919 and Angew. Chem. Int. Ed. 2012, 51 (10), 2375-3378,the State Key Lab of Materials-Oriented Chemical Engineering stepped onto a new level in the preparation, assembling and application of high performance of nano-materials.
