Microwave-assisted one-step green synthesis of amino-functionalized fluorescent carbon nitride dots from chitosan.

We present an economical, facile and effective microwave pyrolysis approach to synthesize highly amino-functionalized fluorescent carbon nitride dots (CNDs). The formation and the functionalization of CNDs was accomplished simultaneously through the dehydration of chitosan. It is suggested that these CNDs have good water solublility and exhibit strong fluorescence.
