| Abstract | As the amount of biomass waste continues to increase, there is a growing need for innovative solutions. Biomass waste derived carbon dots (BWCDs) are a promising way to convert waste into valuable materials in a sustainable and environmentally friendly way. These biocompatible dots, with their abundant raw materials and customizable properties, offer versatile solutions in both dissolved and solid forms. While both forms offer advantages, BWCDs in the solid state are characterized primarily by improved stability, tailored functionalities, and increased emission. However, the widespread use of solid-state BWCDs is hindered by several obstacles. In this review, the unique properties and synthesis methods of carbon dots are explained. Various techniques such as hydrothermal and microwave-assisted methods for synthesizing BWCDs and their effects on biomass precursors are examined. Strategies for the preparation of BWCDs in the solid state that improve stability and functionality are described. Applications in the field of optoelectronics and materials science emphasize their versatility. Although efficiency and long-term stability are a challenge, the report gives an outlook on future developments. It emphasizes the promise of BWCDs as environmentally friendly alternatives and embodies the fusion of waste recycling and advanced materials science that drives technological innovation. |
