声学驱动的单个气泡，悬浮在水中，沿着与声致发光（SL）信号的径向动力学，记录在不存在和存在的微摩尔量的不同的表面活性剂和聚合物。据观察，这些非挥发性溶质，在低浓度范围内使用，没有显着影响的径向动力学，也没有SL强度的一个单一的气泡在水中。相比之下，添加微摩尔量的挥发性溶质戊醇，其猝灭程度与SL的90%相似，而不会影响气泡的径向动力学。
The radial dynamics of an acoustically driven single bubble, levitated in water, along with the sonoluminescence (SL) signal, were recorded in the absence and in the presence of micromolar quantities of different surfactants and polymers. It was observed that these nonvolatile solutes, in the low concentration range used, did not significantly affect the radial dynamics nor the SL intensity of a single bubble in water. In contrast, the addition of micromolar quantities of a volatile solute, pentanol, quenched similar to90% of the SL without affecting the radial dynamics of the bubble.
