Carbon quantum dots possess excellent physiochemical properties, high photostability. In this work, fabrication of boron functionalised nitrogen doped carbon quantum dot was achieved to detect harmful pollutant as picric acid. Firstly, nitrogen doped CQD was synthesized by rapid microwave approach from L-serine and citric acid which acts as precursor. Then functionalisation with boric acid under reflux condition to obtain B/N-CQD.</text>
