Review on Synthesis, Characterization and Applications of Silver Sulphide Quantum Dots

Quantum dots (QDs) provide a powerful material to engineer various optoelectronics devices as well as it provides many opportunities in the biomedical field. QDs have received a great attention due to their significant properties. QDs are one of the foremost nanotechnologies to be incorporated with the biological sciences and are extensively projected helpful for application in a number of profitable consumer and clinical products. They exhibit unique luminescence characteristics and electronic properties such as wide and continuous absorption spectra, narrow emission spectra, and high light stability. In this review paper we will focus on synthesis method, characterization techniques for quantum dots and biomedical applications of silver sulphide (Ag2S) QDs as they are less toxic as compare than CdSe, PbSe, CdS quantum dots. Silver sulphide quantum dots are widely used in bio medical applications.
