Abstract
AbstractCarbonized polymer dots (CPDs) exhibiting tunable solid‐state emission (SSE) show great promise as rare‐earth‐free functional phosphors. Nevertheless, progress in this field has been hindered by the structural heterogeneity of CPDs and a lack of fundamental understanding of the underlying emission mechanisms. In this work, a universal approach is presented for the large‐scale, controlled synthesis of CPDs with tailored SSE properties. This strategy leverages intraparticle Förster resonance energy transfer (FRET) by incorporating selected fluorophores into self‐assembled CPDs nanostructures. The resulting CPDs exhibit exceptional SSE characteristics, such as high quantum yields, adjustable band structures, narrow emission linewidths, and excellent photostability in both solution and solid‐state. Moreover, the multifunctional capabilities of these CPDs are demonstrated, including efficient light harvesting, their potential as nanocarriers, and their application in light‐emitting diodes (LEDs). This findings establish self‐assembly‐mediated doping as a robust platform for engineering CPDs with unique SSE properties, underpinned by the principles of intraparticle FRET.
