Nanoparticles of Ag-In-S and Cu-In-S in Aqueous Media: Preparation, Spectral and Luminescent Properties

Results are summarized for studies of the spectral and luminescent properties of nonstoichiometric nanoparticles (NP) of Ag-In-S (AIS) and Cu-In-S (CIS) obtained in aqueous solutions. Using AIS NP stabilized by mercaptoacetate anions as an example, feasibility was demonstrated for size-selective pre...

Description
Summary:Results are summarized for studies of the spectral and luminescent properties of nonstoichiometric nanoparticles (NP) of Ag-In-S (AIS) and Cu-In-S (CIS) obtained in aqueous solutions. Using AIS NP stabilized by mercaptoacetate anions as an example, feasibility was demonstrated for size-selective precipitation for the separating out various sizes of nanoparticles from a colloidal ensemble of these particles, which display photoluminescence quantum yield up to 45%-46%. The prospects for further studies in this field and the development of potential applications of luminescent CIS and AIS in aqueous media are discussed.
