Recently, Carbon dots (CDs) have received considerable attention because of the light-emitting characteristics, biocompatibility, chemical stability. CDs based on PEI(polyethyleneimine) is one step microwave-assisted synthesis. The PEI CDs showed strong blue emission at 415 nm and multicolor photoluminescence under different excitation illuminations. Thus, it have broad excitation spectra region and tunable emission wavelength. The synthesis process as a whole of these reaction is very simple and scalable method because these method don`t need adjust equivalent by using only one polymer. It is expected to various applications such as bioimaging, biosensing, transistor and education. 2016년 한국교통대학교 지원을 받아 수행하였음. |
