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.
