Hydrothermal synthesis and hydrothermal treatment of AgInS2/ZnS luminescence quantum dots

In this contribution, we report synthesis of water-soluble Ag−In−S /ZnS quantum dots (QDs) using low toxic precursors as well as investigation of their optical properties. The QDs were successfully obtained directly in an aqueous environment in two ways: traditional one-pot water synthesis and hydrothermal synthesis in the presence of thioglycolic acid as a stabilizing and reactivity controlling agent. The effect of hydrothermal treatment on water-soluble Ag−In−S/ZnS QDs was shown and it was found that they are resistant for 4 hours autoclaving.
