The study presents the synthesis and characterization of CdxZn1-xS-based nanocomposite materials, using the sonochemical and the Successive Ionic Layer Adsorption and Reaction (SILAR) approach. In the sonochemical approach, Cd0.4Zn0.6S nanoparticles were synthesized using three various stabilizers-polyvinyl alcohol (PVA), 3-mercaptopropionic acid (3-MPA), and styrene for analysis the effect of stabilizers on nanoparticle properties. CdxZn1-xS/PVA nanocomposites with varying cadmium-to-zinc ratios (x = 0.2, 0.4, and 1) were synthesized using the same sonochemical approach to study their structural, optical, and morphological properties. Meanwhile, CdxZn1-xS/PVA nanocomposites (x = 0.1, 0.2, 1) were prepared using the SILAR approach, as well as Cd0.2Zn0.8S nanocomposites at various synthesis temperatures (25 degrees C, 45 degrees C, and 65 degrees C). From the comparison of nanocomposite materials with the same stoichiometric composition by both approaches, it was determined that CdxZn1-xS compound is formed in phase with hexagon in ternary compounds, regardless of the type of used stabilizer and particle size. In binary compounds, the formation of a hexagonal phase is observed using the SILAR approach, and a cubic phase is observed using the sonochemical approach. There are significant differences in the E-g value of CdxZn1-xS -based composite materials during the synthesis of the same composite material by two different approaches. Red shift by sonochemical approach and blue shift prevails during synthesis by SILAR approach. Certain shifts between the two approaches in the determination of chemical bonds are associated with differences in the metal-sulfide bonding environment, which may be affected by the different particle sizes produced by the different synthesis approaches.
