Recently, carbon quantum dots have attracted attention as various advantages such as chemical inertness, lack of blinking , variable fluorescence emission, low cytotoxicity and good biocompatibility as compared with semiconductor quantum dots and organic dyes. In addition, CQD doped with heteroatoms have local surface chemical and electronic properties, thus having adjustable properties in biosensors and bioimaging. We synthesize N-doped carbon quantum dots by urea and citric acid in a single-stage microwave synthesis. The N-doped carbon quantum dots were characterized by TEM, FTIR, fluorescence spectrophotometer and uv - visible spectrophotometer. The N-CQDs exhibit fluorescence characteristics in excitation wavelength-dependent emission and strong fluorescence excitation bands are present at 360 nm and 440 nm.
