ABSTRACT = {A new type of Ag<sub>2</sub>S-CdS/Ag/GNP nanocomposite material was successfully synthesized in 
the presented work. The structural and physical properties of compounds were studied 
separately and together. Ag<sub>2</sub>S-CdS/Ag/GNP nanocomposite materials were studied by Xray
 diffraction (XRD), Ultraviolet-Visible (UV-Vis), Fourier Transform Infrared (FTIR), 
Raman spectroscopy and Scanning Electron Microscopy (SEM). Based on the results, Ag 
nanowires (NWs) were successfully synthesized, and then it was determined that during the 
hybridization process, two phases of acanthite Ag<sub>2</sub>S and the cubic crystal system of Ag<sub>2</sub>O 
were formed. Then, Ag<sub>2</sub>S-CdS NWs were formed from mixed monoclinic 
Ag<sub>2</sub>S and hexagonal CdS. In the absorption spectrum of Ag NWs, the main absorbance 
peaks were observed at 357.3 nm and 380.2 nm. The energy gap (Eg) values of the Ag 
sample are 3.8 eV. The band gap value of Ag<sub>2</sub>S (2.5, 3.8, 4.6 eV) and Ag<sub>2</sub>S-CdS (2.5, 3.8, 
4.8 eV) have a triple value due to the formation of a hybrid structure. The Raman spectrum 
of Ag<sub>2</sub>S-CdS belongs to longitudinal-optical (LO) phonon modes of zinc-blende phase CdS 
and for the 1, 2, and 3 times spin-coated samples on the surface of GNP/PVA have observed 
all characteristic Raman peaks, which belong to NWs at 485.13 cm<sup>-1</sup>
, and 960.22 cm<sup>-1</sup>
