Synthesis and physicochemical properties of AgInS2 nanoparticles

Abstract

The semiconductor material of group I-II-VI, AgInS2, due to its unique photoelectric and catalytic properties, is widely used in the field of photovoltaic solar cells and low-toxic photostable molecular analyzers. The advantages of these quantum dots (QDs) are that their properties can be altered not only by changing the size of the quantum dots, but also by changing their composition, the ratio of concentrations of precursors and stabilizer, the nature of the stabilizer, the temperature of the mixture during synthesis and post-synthetic heat treatment, and the formation of a passivating membrane.
