Abstract: The influence of UV irradiation on the formation of molecular silver clusters in aqueous solutions containing silver, zinc, magnesium nitrates, and polyvinylpyrrolidone has been studied. Solutions and coatings have been investigated using optical and luminescent spectroscopy methods, the morphology of coatings has been analyzed by electron microscopy. It has been shown that irradiation significantly accelerates the processes of reduction of silver ions and of formation of molecular clusters and silver nanoparticles stabilized by polyvinylpyrrolidone.

Keywords: solution, luminescence, Ag molecular clusters, nanoparticle.
