“…It is generally known that the Ag 2 S shows the outstanding photoluminescence properties . Recently, the studies found that the nanostructured monoclinic Ag 2 S has the defect crystal structure with vacancies in the silver sublattice and this structure is preserved in the Ag‐Ag 2 S heterodimer . Thus, Ag‐Ag 2 S heterodimer has received great interest for its unique optoelectronic and novel properties from metal, semiconductor or their synergistic effects, like photoelectron transmission between metal and semiconductor and tunable local surface plasmon resonance (LSPR) based on morphology and composition .…”

Ag-Ag 2 S heterodimers with good dispersibility were prepared in polyethylene glycol 400 (PEG400) at 160°C. The possible formation mechanism was proposed along the "CH 3 COOAg/Ag 2 S-Ag 2 O/Ag 2 S-Ag/Ag 2 S" route. The products [a] Figure 4. (A) The XRD patterns of the products from the mixture of PEG400, AgNO 3 and S powder: (a) 100°C, 10 min, (b) 100°C, 30 min, (c) 120°C, 10 min. (B) The possible growing mode of Ag-Ag 2 S heterodimers.4052 uid was obtained. The postprocessing of the products were the same as that of the Ag-Ag 2 S heterodimers. Preparation of Ag 2 S Nanomaterials4 mmol sulfur powder were weighed into a 100 mL round flask while some 40 mL PEG400 and 1 mmol AgNO 3 were added. The mixture was kept at 100°C for 10 min under mild magnetic stirring and then the black turbid liquid was obtained. The postprocessing of the products were the same as that of the Ag-Ag 2 S heterodimers. Conflicts of InterestThere are no conflicts to declare.

“…Silver sulde Ag 2 S, which is a semiconductor below $450 K and a superionic conductor at T > 452 K, is one of the most important suldes. 20 Application of nanostructured silver sulde holds much promise in microelectronics, where Ag 2 S/Ag heteronanostructures and nanocomposites are used in nonvolatile memory devices and resistive switches. [21][22][23] Their action is based on the phase transition of acanthite a-Ag 2 S into argentite b-Ag 2 S. [12][13][14][23][24][25][26][27][28] According to the phase diagram of the Ag-S system, 29 silver sulde Ag 2 S has three polymorphic modications.…”

For the first time, the a-Ag 2 S (acanthite)-b-Ag 2 S (argentite) phase transition in a single silver sulfide nanoparticle has been observed in situ using a high-resolution transmission electron microscopy method in real time. Colloid solutions of Ag 2 S nanoparticles and nanostructured powders of silver sulfide have been synthesized by one-stage chemical bath deposition from an aqueous solution of silver nitrate, sodium sulfide and sodium citrate. Ag 2 S nanoparticles were heated to different temperatures directly in an electronic microscope by regulating the energy of the electron beam. This allowed observation of the transition of acanthite into argentite and the reversible transition of argentite into acanthite in real time, and this phase transition to be filmed. Temperature dependence of the lattice constant a arg of argentite b-Ag 2 S in the temperature range 448-723 K is established by in situ high-temperature X-ray diffraction.The orientation relationships between the monoclinic acanthite a-Ag 2 S and the body-centered cubic argentite b-Ag 2 S are determined. It is shown that the possible distances between silver atoms in cubic argentite, in contrast to those in acanthite, are too small for the positions of the metal sublattice to be occupied by Ag atoms with a probability equal to 1. † Electronic supplementary information (ESI) available: Experimental details of synthesis and evidence of silver sulde nanoparticles, crystal structure of acanthite and argentite phases of silver sulde, and movie of the phase transformation of acanthite into argentite in real time.
