Single Bubble Sonoluminescence

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.

Single Bubble Sonoluminescence

Discovered the activation of moving single-bubble sonoluminescence and radioluminescence for Gd3+ and Dy3+ ions in aqueous solutions of GdCl3 and DyCl3 by the acceptor of a hydrated electron (eaq-): H+, Cd2+, etc. This activation is similar to the previously found activation by acceptors of eaq- radioluminescence and single-bubble sonoluminescence for the Tb3+ ion. Electron acceptors do not affect the quantum yield of the said lantha-nide ions photoluminescence. They also do not affect the yield of their multibubble sonoluminescence in aqueous solutions, since eaqdoes not appear in significant amounts during multibubble sonolysis. The found luminescence activation effects of lanthanide ions are interpreted as a consequence of the suppression of the quenching (reduction) reactions of these electronically excited ions eaq: *Ln3+ + eaq- → Ln2+ by acceptors. The feasibility of these reactions was predicted for all Ln3+ ions based on a theoretical estimate of their free energy. The discovery of the described effects of activation of the luminescence of Ln3+ ions is a consequence and serves as confirmation of not only the known generation of eaq- during radiolysis, but also its previously unknown generation during moving single-bubble sonolysis of water.

Single Bubble Sonoluminescence

Single-bubble sonoluminescence (SBSL) is a light-emission event from a stably oscillating bubble trapped at the pressure anti-node of a standing ultrasound wave, a phenomenon that has been studied intensively for a decade [1]. Using ceramic piezoelectric transducers PZT, we are able to irradiate a liquid inside a resonator flask by means of an ultrasound wave, and we eventually capture a bubble inside a restricted domain in the aqueous medium. The trapped bubble will expand and collapse at an accelerated rate, emitting light. To capture the bubble we perform some experiments using differently sized and shaped piezoelectric transducers, and we manage to verify their capacitance and impedance behavior in our sonoluminescence circuit. Our experiments were performed at Laboratory of Experimental and Applied Physics (LaFEA) at CEFET-RJ.
