QUANTUM DOTS: SYNTHESIS, PROPERTIES AND APPLICATIONS

The size dependent property arising from quantum dot confinement effect leads the way towards many promising applications including flexible electronics, optoelectronics, biomedical, etc. Synthesis of certain QDs (PbS) remains challenging due to their high reaction rate. Since size and chemical composition are tuneable, thus the properties of these QDs may be controlled and used over wide range of applications in various fields. In this paper the synthesis PbS quantum dot is discussed along with the important characteristics and applications in various fields. Moreover, the advantages of QLEDs in the field of display electronics are discussed which lays foundation for advance wearable devices. The application of QDs which they offer in medical field including detection and treatment of various categories of cancers, with almost negligible side effects is also covered here in this article.
