Abstract
Chalcogenides nanocrystals, one of the emerging hot topics in the field of research offers the characteristics that are unparalleled by conventional materials in their respective field of applications. In recent years, chalcogenides nanocrystals are holding significant impact in various applications such as lighting, displays, photovoltaics, sensors, imaging devices, etc. owing to their shape, size and tunability of composition. Moreover, most of the chalcogenides nanocrystals are deployed in large-scale devices due to its sustainability, inexpensive and environmentally friendly. This chapter emphasizes the concise overview of chalcogenides nanocrystals, sketching the state of the art of synthesizing materials along with strategies to circumvent the limitations arise during ternary and quaternary compositions. A discussion highlighting on shape, size, composition controlled growth of chalcogenides are provided. Followed by the synthesis, functional properties (structural, optical, electronic and magnetic) and its ubiquitous applications are addressed in a detailed manner. Finally, as a summary, track of the rapidly advancing field and their key challenges have been discussed.
