“…Due to the effect of morphology and size on the properties of metal oxide NPs, their synthesis techniques mainly focus on these two parameters (Maduraiveeran et al, 2019). Among MONPs, the transition metal oxides have drawn much notice due to their outer electron configuration (Velmurugan and Incharoensakdi, 2018) Among various classes of metal oxide NPs, II-VI class inorganic semiconductor nanomaterials like Zinc Oxide (ZnO), Cadmium Sulfide (CdS) and Zinc Sulfide (ZnS) have emerged as important materials for the applications in photovoltaic and optoelectronics devices (Abbasi et al, 2017). High chemical stability, inexpensive and easy synthesis methods and fast optical response speed lead to the use of them in non-linear optical devices such as optical switchers (Koushki et al, 2014a).…”

In this study, a composite of zinc tungsten oxide nanoparticles (W-ZnO NPs) has been synthesized via mixing Na2WO4 and zinc acetate in water, followed by dropwise addition of NaOH. The synthesized W-ZnO NPs were characterized using measurement methods such as XRD, dynamic light scattering (DLS), Scanning electron microscopy (SEM) and UV-Vis. Also, the results were compared with the pure synthesized ZnO and WO3 NPs. Non-linear optical properties of the synthesized composite were measured using the Z-scan technique with a continuous wave Nd-Yag laser. The negative non-linear absorption coefficient of the components was obtained which indicates that the saturation absorption occurred in this composite. In comparison with pure ZnO NPs, non-linear absorption decreases which can be attributed to the negligible optical response of WO3 structures. Also, the negative value of the close aperture Z-scan curve shows that the thermal lensing effect is the main reason for the third-order non-linear refraction.
