Abstract: Precipitation of PbS quantum dots (QDs) controlled by solid-state Ag+ ion migration and subsequent thermal treatment was investigated. Ag+ ions migrated from Ag paste applied on the surface into glass at 320°C. After following heat treatment, PbS QDs formed in the near surface area where Ag paste was coated. Sizes of the PbS QDs were larger in Ag+-migrated surface regions than those in Ag+-free glasses, and PbS QDs can grow at temperatures as low as 420 and 430°C. Ag nanoparticles (NPs) also formed during the thermal treatment. These results suggest that Ag NPs supplied the nucleating sites and promote the formation of PbS QDs in glasses. The spatial distribution of PbS QDs in glasses can also be controlled through solid-state Ag+ ion migration.
