This study is devoted to the systematic study of the synthesis, modification and physicochemical properties of multicomponent CuInS2/ZnS quantum dots (QDs). Within the framework of the study, the methods for synthesizing CuInS2 cores and epitaxially growing ZnS shells were optimized. Various ligand exchange and surface modification strategies were used to passivate the surface of QDs, increase colloidal stability and functionalize them for biomedical purposes. The size, shape, crystallographic structure, elemental composition and surface chemistry of the synthesized CuInS2/ZnS QDs were studied using various modern instruments. The results of the study proved that the ZnS shell and surface modification play an important role in improving the photostability and quantum yield of CuInS2/ZnS QDs. The prospects of QDs in various fields of application, in particular, targeted drug delivery and lighting devices, were evaluated based on experimental data. This research serves as an important basis for the development of QDs technologies and the expansion of their practical application.
