In this work, gold nanoparticles (AuNPs) were created utilizing a plasma jet method and 0.5 gm/mol of gold salts (4H2O•HAuCl4) with varied flow diameters (0.6 mm, 0.8 mm, 1 mm, and 1.2 mm). The gas flow changes according to the system diameter (2,2.4,3.4, and 3.6 L/min, respectively). X-ray diffraction, ultraviolet, visible spectra, and FESEM were each used to investigate the nanoparticles. The XRD pattern revealed that the film's extreme peaks reflect crystallinity, with an average crystallite size of (18–26) nm and a face-centered cubic structure. The surface plasmon resonance for colloidal AuNPs produced in the UV was at 536–540 nm.A field emission scanning electron microscope (FESEM) was used to look at the morphology of the Au

In the present study, we intend to evaluate the effect of temperature on the structural, morphological, and optical properties of tin oxide. For this purpose, tin oxide micro-flowers were prepared by the hydrothermal method at two different hydrothermal temperatures of 130 and 150°C.
