❖ Pure Silver Sulfide (Ag S) were synthesized via co-precipitation technique and
2
annealed at various temperatures.
❖ Structural aspects, including crystallite size (41-52 nm) were analyzed, and
nanophase was confirmed using the X-ray diffraction technique.
❖ Optical characterization of as-synthesized samples was analyzed using UV
o
techniques, and the 200 C and 400 C.
