Abstract
Colloidally prepared copper sulphide (Cu2-xS) nanocrystals are possessing superior structural and optical properties owing to the presence of copper vacancies. The application of colloidal Cu2-xS nanocrystals are critically analysed for several optoelectronic applications. Furthermore, colloidally prepared Cu2-xS nanocrystals undergo facile process such as cation exchange, additives induced structural modifications etc. Therefore, it is important to evaluate the optical properties of these nanomaterials in order to apply them for future optoelectronic applications. Out of other properties, localized surface plasmon resonance (LSPR) by controlling composition of the Cu2-xS nanocrystals is investigated with more curiosity and much useful findings are derived for the potential applications. Because of the near-infra-red (NIR) absorption, the spectral absorption could be tuned and the LSPR arising from the non-stoichiometric Cu2-xS nanocrystals could be used for numerous applications. This chapter discusses about the current developments associated with the colloidally prepared Cu2-xS nanocrystals and their LSPR property in several potential applications. The experimentally demonstrated results are compared with the future predictions in this research area.
