Abstract:Carbon polymer dots (CPDs) show incredible potential due to their outstanding optical characteristics, simple synthesis using low-cost precursors, and diverse applications. This study aimed to develop chromium-doped CPDs (Cr-CPDs) using an efficient one-step microwave method for fluorescence sensing and optoelectronic devices. The one-pot microwave synthesis used citric acid, urea, C 6 H 9 O 6 Cr, and N,N-dimethylformamide. The resulting Cr-CPDs demonstrated excitation-dependent photostability with a high fluo… Show more
