Quantum dots are the current research hotspot, among which graphene quantum dots (GQDs) are the most attractive. Zero-dimensional graphene quantum dots produce band gaps due to their quantum confinement effects and boundary effects, which break the special zero band gap structure of graphene, excite stable fluorescence, and make the application of graphene in the biological field possible. GQDs have good biocompatibility, low toxicity, and stable photoluminescence characteristics.
The stable photoluminescence scene characteristics of GQDs are particularly useful for up-conversion nanoparticles (UCNP) because stability is essential for controlled experiments and applications. Since UNCPs allow for less energy, the trend toward energy efficiency will surely continue, and GQDs can certainly be implemented in that process. GQD and UNCP will undoubtedly improve medical technology and energy research together. We are glad to take part in producing improved bioimagining and supply products that can be integrated into solar cells.
