HIGHLIGHTS
- who: Junming Zhang and colleagues from the College of Physics and Optoelectronic Engineering, Ocean University of China, Qingdao, China have published the article: Photophysical Properties of Bright Luminescent Polyethyleneimine, in the Journal: Photonics 2023, 262 of 18/01/2023
- what: The main reason is that both of PEI and L-Glu were grafted onto the CNDs, and PEI has higher N content.
SUMMARY
Carbon dots (CDs), as a new branch of carbon-based nanomaterials, were first discovered in 2004. So far, various kinds of CDs have been synthesized, including carbon nanodots . . .
