Design, Synthesis, and Characterization of Graphene Quantum Dots

Dear Colleagues,

Graphene quantum dots, which are zero-dimensional graphene nanostructures, have attracted significant attention due to their unique properties and potential applications in various fields, including optoelectronics, energy storage, biomedicine, and catalysis. The Special Issue on "Design, Synthesis, and Characterization of Graphene Quantum Dots" aims to provide a comprehensive platform for researchers, scientists, and engineers to share their cutting-edge research, methodologies, and findings related to GQDs.

Considerable progress has been made in the research on GQDs, leading to advancements in their synthesis methods, structural characterization, and understanding of their properties. Researchers have developed various approaches for GQD synthesis, including bottom-up and top-down methods, chemical vapor deposition, solution-phase methods, and electrochemical synthesis. Structural and morphological characterization techniques have been employed to investigate the size, shape, crystallinity, surface chemistry, and defect engineering of GQDs. Additionally, studies have focused on elucidating the optical and electronic properties of GQDs, exploring their absorption, emission, quantum confinement effects, energy band structure, charge carrier mobility, and conductivity.

However, despite the significant progress made, there still exist gaps in our understanding of GQDs that need to be addressed. One crucial research gap lies in the development of scalable and efficient synthesis methods that can yield GQDs with precise control over their size, shape, and surface properties. Another critical area that requires attention is the comprehensive understanding of the relationship between the structural characteristics of GQDs and their optical and electronic properties. Furthermore, the translation of GQD research into practical applications and device integration is an area that demands further exploration. While GQDs have shown promising potential in various fields, such as optoelectronics, energy storage, and bioimaging, there is a need to bridge the gap between fundamental research and real-world applications. Investigating the performance optimization of GQD-based devices, exploring their stability, and addressing potential challenges are crucial steps towards their successful integration into practical technologies.

In summary, this Special Issue on "Design, Synthesis, and Characterization of Graphene Quantum Dots" aims to build upon the existing research in the field and address the current gaps. By focusing on scalable synthesis methods, understanding the structure–property relationships, and exploring applications and device integration, this Special Issue seeks to advance the field of GQDs and pave the way for their widespread utilization in diverse technological domains.
