Abstract
Quantum dots (QDs) have emerged as versatile nanomaterials with exceptional optical, electronic, and chemical properties, enabling wide-ranging applications in bio-imaging, photovoltaics, sensors, and optoelectronic devices. However, conventional synthesis methods often involve toxic solvents, high energy input, and hazardous by-products, raising significant environmental and health concerns. To address these challenges, green synthesis approaches have gained increasing attention as sustainable alternatives. These strategies utilize eco-friendly precursors, plant extracts, microorganisms, and benign reaction media to produce QDs with tunable size, morphology, and surface chemistry. This review provides a comprehensive overview of the principles, recent progress, and methodologies of green synthesis of QDs. Emphasis is placed on the role of biological systems, low-toxicity chemicals, and renewable resources in achieving high-quality nanocrystals. Additionally, challenges such as scalability, reproducibility, and performance optimization are discussed, along with potential future directions in integrating green QDs into practical devices. By highlighting advances in eco-conscious synthesis, this article underscores the potential of green nanotechnology in driving safer and more sustainable applications of quantum dots.
