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 fluorescence 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 response 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.

The tunability of CQDs' photoluminescence arises from their size-dependent electronic structure.

As the size of the CQDs decreases, the energy gap between valence and conduction bands increases, resulting in a shift to higher energy emissions. Furthermore, the surrounding environment can also influence the photoluminescence properties of CQDs. For example, changes in pH, temperature, or the presence of molecules can alter the electronic structure and thus affect their emission spectra.

Incorporating CQDs within SWCNTs offers a platform for exploring the interplay between these factors. The type and chirality of the SWCNT host can influence the energy levels and charge transfer processes within the system, ultimately modulating the characteristics of the encapsulated CQDs. This tunability holds immense potential for applications in diverse fields graphene manufacturing such as bioimaging, sensing, and optoelectronic devices.
