Abstract: For the first time, luminescence of Ag atoms was recorded during moving single-bubble sonolysis of silver nanoparticles aqueous colloidal suspension. This glow is caused by the entry of nanoparticles into a bubble deformable during motion and their decomposition to atoms with collisional excitation in the nonequilibrium plasma of the bubble. Nanoparticles were obtained by multibubble sonolysis of an AgNO$_3$ solution with the addition of honey. This method was used to synthesize a stable suspension of Ag nanoparticles with an average size of $\sim$10 nm. By comparing the experimental spectrum of this suspension and simulated spectra of Ag, the electron temperature in the bubble plasma was found to be $\sim$10000 K.

Keywords: single-bubble sonoluminescence, silver nanoparticles, electron plasma temperature.
