奎宁水溶液中单泡声致发光的荧光观测
Observation of Fluorescence Emissions from Single-Bubble Sonoluminescence in Water doped with Quinine
摘要：
声致发光是一种将声音转换为光的现象。详细的机制以及能量聚焦潜力尚未完全探索和理解。到目前为止，只观察到可见光子，而紫外线范围内的发射仅被推断。将荧光染料奎宁掺入稀硫酸溶液中，可以将高能光子转换成衰减常数较慢的可见光子。这些声致发光和荧光发射被同时观察到，并且这两种模式的发射信号可以通过它们各自的时序分布来区分。计划使用这种技术作为诊断工具，定量研究紫外线和其他高能量的声致发光发射进行了讨论。
英文摘要：
Sonoluminescence is a phenomenon involving the transduction of sound into light. The detailed mechanism as well as the energy-focusing potentials are not yet fully explored and understood. So far only optical photons are observed, while emissions in the ultra-violet range are only inferred. By doping the fluorescent dye quinine into water with dilute sulphuric acid, the high energy photons can be converted into the optical photons with slower decay constants. These sonoluminescence and fluorescent emissions were observed in coincidence, and the emitted signals of the two modes can be differentiated by their respective timing profiles. Plans for using this technique as a diagnostic tool to quantitatively study ultra-violet and other high energy emissions in sonoluminescence are discussed.
