Tunable Photoluminescence of Carbon Quantum Dots Encapsulated within SWCNTs

Carbon quantum dots (CQDs) are a fascinating class of nanomaterials exhibiting tunable photoluminescence properties. Their inherent radiance arises from the quantum confinement effect, where electrons confined to nanoscale dimensions display quantized energy levels. Encapsulation of CQDs within single-walled carbon nanotubes (SWCNTs) presents an intriguing strategy for enhancing their luminescent properties. The unique structural and electronic properties of SWCNTs can influence the optical behavior of encapsulated CQDs, leading to a synergistic enhancement in photoluminescence. This encapsulation approach offers several strengths, including improved stability, reduced clustering, and fine-tuned luminescent emission.
