Abstract
En 中文
Carbon dots (CDs) are a fascinating area of research. Carbon nanodots (CDs); also known as carbon quantum dots (CQDs); carbon nanodots (CNDs); and graphene quantum dots (GQDs); have garnered increasing attention in recent times due to their accessibility; non-toxicity; and affordability as carbon-based materials. This paper highlights several synthetic approaches for creating CDs; including hydrothermal synthesis; pulsed laser ablation; direct carbonization; microwave and ultrasonic aided chemical synthesis; and electrochemical methods. Moreover; CDs also possess excellent photostability as they can maintain their optical properties like photoluminescence (PL); charge transfer properties; etc.; even under prolonged light exposure. Owing to their distinct optical and optoelectronic characteristics; C-dots have the potential to serve as crucial components for several fields; including optoelectronics; solar cells; light-emitting diodes; and sensitizers. In addition to encouraging the practical implementation of CDs in many current and future research lines; we hope that the material presented in this review will stimulate further fascinating study on CDs from a fresh angle.
