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.

Abstract Long‐lived room temperature phosphorescence (RTP) materials have many potential applications in areas such as luminescent lighting, biological imaging, and information security owing to their unique optical properties. However, traditional RTP are challenged by the fact that can be easily quenched dissolved oxygen solvent‐assisted relaxation, making it difficult for them emit aqueous solutions, particularly extreme pH environments. In this study, a multicolor carbon dot‐based composite material (u‐CDs) is developed with urea 3‐aminophenylboronic acid raw materials. This exhibits ultra‐long emission lifetime high stability constructing rigid hydrogen bond network structure an environment. The u‐CDs optimal of 448 nm, quantum yield 21.6%, 2.35 s, afterglow time more than 50 s. With properties, great anti‐counterfeiting, encryption, 3D printing.
