We report a rational synthesis of carbon nanodots (CNDs) aimed at tailoring their emission, starting from a reasoned choice of organic precursors. To showcase the potential of this approach in a field such as optoelectronics, we designed experiments aimed at preparing materials that emit across the entire visible spectrum. Specifically, using precursors such as arginine, ethylenediamine, naphthalene dianhydride, and 2,6-dibromonaphtalene dianhydride, in appropriate ratios, it was possible to obtain pure white-light (0.33, 0.33; CIE coordinates) emitting carbon nanodots (WCNDs) through a one-step microwave-assisted synthesis and facile purification. The characterization and properties of this novel nanomaterial is discussed.
我们报告了一种合理合成碳纳米点（CNDs）的方法，旨在通过合理选择有机前体制备发射可调谐的碳纳米点。为了展示这种方法在光电等领域的潜力，我们设计了实验，旨在制备发射整个可见光谱的材料。具体来说，使用精氨酸、乙二胺、萘二酐和 2,6-二溴萘二酐等前体，以适当的比例，通过一步微波辅助合成和简单的纯化，有可能获得纯的白光（0.33，0.33；CIE 坐标）发射碳纳米点（WCNDs）。本文讨论了这种新型纳米材料的特性和性能。
