Quantum Dots Based Nanocomposites

This chapter explores the topic of quantum dots-based nanocomposites, providing a synopsis of their fabrication, characterisation, and varied practical applications. The unique qualities of quantum dots as building blocks are discussed, along with their relevance in fields such as photovoltaics, optoelectronics, biomedicine, and environmental monitoring. This chapter focuses on the cutting-edge techniques used to create them and highlights the importance of adapting their size, shape, and composition to a variety of uses. Characterization methods are presented in detail for understanding charge transfer, energy transfer, and interfacial interactions in nanocomposites. Examples of their use in solar cells, LEDs, targeted medication delivery, bio imaging, and environmental clean-up demonstrate their potential for far-reaching influence. Future directions for realising the full potential of quantum dots-based nanocomposites in advancing nanotechnology towards a sustainable and efficient future are also discussed in this chapter, along with obstacles relating to safety, scalability, and technological hurdles.
