Abstract

Photographs and spectra of single-bubble sonoluminescence of a bubble moving in pure water and aqueous solutions of \({\text{Ru}}({\text{bpy}})_{3}^{{2 + }}\) are obtained. It is shown for ruthenium complex solutions that there are luminescence regions outside the main trajectory of motion of the luminous bubble, which are absent in pure water. The observed spatial localization of these regions confirms that (as we have shown previously) they are caused by sonochemiluminescence of the ruthenium complex in the solution bulk that is secondary relative to the primary sonoluminescence of the bubble.

液体声场中两种类型的发光的可视化

摘要

在纯水和\（{\ text {Ru}}（{\ text {bpy}}）_ {3} ^ {{2 +}} \）的水溶液中移动的气泡的单气泡声致发光照片和光谱获得。对于钌络合物溶液，显示出在发光气泡的主要运动轨迹之外存在发光区域，该发光区域在纯水中不存在。观察到的这些区域的空间定位证实（如我们先前所示），它们是由溶液中钌配合物的超声发光引起的，该溶液相对于气泡的主要超声发光是次要的。
