The preparation of powder forms, structural tuning, and performance optimization of these N-GQDs have become prominent research focuses in the field of nanomaterials. Technical Parameter 外观 Appearance 白色至浅黄色粉体White to pale yellow powder N含量 N content 47at.% (XPS) Product Features 1)One of the most prominent advantages of N-GQDs powder is its tunable and highly efficient photoluminescence (PL) properties. By systematically adjusting synthesis parameters—such as precursor ratios, reaction temperature, reaction time, and the type of nitrogen source—the emission wavelength can be precisely tuned to achieve full coverage of the visible spectrum, spanning from blue to red. 2)Secondly, N-GQDs powder exhibits exceptional activity in electrochemical catalysis. The introduction of nitrogen atoms—particularly through the synergistic effect of pyridinic nitrogen (Pyridinic-N) and graphitic nitrogen (Graphitic-N)—can effectively optimize the electronic distribution of the material, generate more active sites, and thereby significantly enhance its catalytic performance. 3)Third, N-GQDs powder exhibits high sensitivity and high selectivity in the fields of environmental monitoring and biosensing. Its surface is rich in oxygen-and nitrogen-containing functional groups, which can engage in specific interactions with particular target analytes, resulting in reversible or irreversible changes in its fluorescence signal and thereby enabling \"on-off\" or \"off-on\" detection modes. Application Fields 1)In the field of biomedicine: N-GQDs powder serves as a key precursor for the preparation of high-performance biomedical imaging probes and drug carriers. Studies have demonstrated that N-GQDs exhibit strong fluorescence emission, high photostability, and low cytotoxicity, making them suitable for fluorescent labeling of living cells and tissues. 2)In the field of sensing, N-GQDs powders have emerged as an ideal platform for constructing high-sensitivity and high-selectivity sensors, owing to their abundant oxygen-and nitrogen-containing functional groups on the surface and their tunable electronic structure. Their fluorescence \"on–off\" switching mechanism has been widely applied in the detection of various metal ions and biomolecules. 3)In the fields of energy and catalysis: the applications of N-GQDs powders are also particularly noteworthy. The introduction of nitrogen atoms effectively modifies the electron cloud distribution of graphene quantum dots, creating abundant active sites, thereby significantly enhancing their electrocatalytic and photocatalytic performance.
