Properties, synthesis, and applications of carbon dots: A review

Carbon Trends, Journal Year: 2023, Volume and Issue: 12, P. 100276 - 100276

Published: June 8, 2023

Carbon dots (CDs) refer to a class of carbon-based nanoparticles with various subgroups based on their crystallinity and morphology. CDs offer tuneable physical, chemical, optical properties, which can be controlled using simple one-pot synthesis techniques. In addition, non-toxicity, biocompatibility, chemical physical responsiveness, resistance photo- chemical-bleaching low cost pave the way wide range applications. The achieved via two approaches: (i) top-down methods, (ii) bottom-up methods. These approaches designed generate intended structures specific band gap, hetero-atom doping, functionality. Further ongoing research enables us understand relationship between structural properties CDs. photoluminescence depends parameters including starting materials, surface states, heteroatom doping etc. Herein, we review such as optical, resulting from particles design. Also, proposed applications biomedicine, light emitting diodes, anticounterfeiting, sensing are presented, where main challenges in strategies overcome these introduced.

Carbon Dots: A Review with Focus on Sustainability

Advanced Science, Journal Year: 2024, Volume and Issue: unknown

Published: July 18, 2024

Abstract Carbon dots (CDs) are an emerging class of nanomaterials with attractive optical properties, which promise to enable a variety applications. An important and timely question is whether CDs can become functional sustainable alternative incumbent nanomaterials, notably inorganic quantum dots. Herein, the current CD literature comprehensively reviewed as regards their synthesis function, focus on sustainability aspects. The study quantifies why it that be synthesized biomass sole starting material free from toxic precious metals critical raw materials. It further describes analyzes employed pretreatment, chemical‐conversion, purification, processing procedures, highlights issues usage solvents, energy efficiency, safety waste management. specially shown many reported methods concerningly wasteful utilization non‐sustainable solvents energy. finally recommended future studies should explicitly consider discuss environmental influence selected material, generated byproducts, quantitative information required amounts consumables, provided evaluation presented in upscaled context.
