Abstract

Shock impact is found to affect the properties of droplets of synthesized colloidal nanoparticles falling on a solid surface. Luminescence of droplets, caused by their impact with a solid surface, is detected. It is established that the luminescence intensity increases with increasing the droplet fall height, nanoparticle concentration, and concentration of molecular oxygen dissolved in the liquid. It is revealed that the reactive oxygen species generation under a shock impact is enhanced by the presence of nanoparticles in the solution.
