The Influence of Ultraviolet Radiation Intensity on the Formation of Silver Nanoparticles by Cavitation-Diffusion Photochemical Reduction

The effect of different intensities of ultraviolet radiation (UV radiation) on the formation of silver nanoparticles (Ag NPs) synthesized by cavitation-diffusion photochemical reduction is studied. It is found out that with a decrease in the UV radiation intensity, the average size of silver nanoparticles increases, while the scatter of Ag NPs diameters increases. It is also noted that with a decrease in the UV radiation intensity by 50% or more, there is an increase in the proportion of organic material in the matrix of the dry residue of the studied solutions, and against the background of the most significant decrease in the level of the studied UV radiation (by 75% of the initial power), nanoparticles are identified on the surface of this organic structure. In addition, the effect of lower intensity UV radiation (
