“…27,28 Size-controlled Ag 2 S QDs have been synthesized by various methods, including the single precursor, 3 one-pot synthesis, 29 hydrothermal, 30 water-phase microwave, 31 liquid-liquid interface reaction, 32 and reverse microemulsion methods. 33,34 The capping agents used to passivate the atoms on the QD surface, which are important to stabilize and prevent the nanocrystalline structures from aggregating, include surfactant (cetyltrimethyl ammonium bromide), 35 sodium dodecyl sulfate, 36 Schiff-base (2-(benzylidene amino)azobenzothiol) ligand, 37 ethylenediaminetetraacetic acid (EDTA), 38 2-mercaptopropioic acid (2-MPA), 10,39 thioglycolic acid (TGA), 40 and or a carboncontaining shells. 41 The objective of this study was to develop NIR active Ag 2 S QDs in a one-pot synthesis with four different Schiff bases (SB) as stabilizing agents.…”
