Abstract

Photographs and spectra of a single-bubble sonoluminescence of a moving bubble in pure water and Ru(bpy)32+ aqueous solutions were obtained. For solutions of the ruthenium complex, the presence of luminescence zones located outside the line of the main trajectory of the glowing bubble characteristic of pure water is shown. The observed spatial localization of these zones confirms the conditionality of their appearance, as was previously shown by the authors, by sonochemiluminescence of the ruthenium complex in the volume of the solution, secondary to the primary sonoluminescence of the bubble itself.
