Foreword

Carbon-based quantum dots (CQDs) have got a lot of attention because of their bright luminescence and strong solubility. CQDs are the potential replacement for the toxic metal-based quantum dots. CQDs are characteristically quasispherical carbon nanoparticles composed of amorphous to crystalline carbon bases. CQDs can be prepared simply and inexpensively by multiple techniques such as the arc-discharge method, microwave pyrolysis, hydrothermal method and electrochemical synthesis. Additionally, CQDs exhibit excellent physical and chemical characteristics like significant crystallization, excellent dispersibility, and photoluminescence attributes. In this book, in-depth deliberation on several potent applications, such as biomedical, water treatment, energy storage, solar cells etc., has been provided. These applications would affect human life quality significantly and have the potential to draw substantial commercial interest.

This book provides a comprehensive guide for researchers and students to understand the overview, properties, synthesis route and applications of carbonaceous quantum dots. This class of quantum dots has recently gained a lot of interest in various fields of basic science and technology. This could be a handbook for various professionals, researchers and students working in the field of biomedical application, green energy, sensing, energy storage, water treatment, etc. Most importantly, this book has proven helpful to postgraduate students in their academic studies.
