声致发光现象是指当液体受到强大声波作用时，液体中会产生一种 “声空化 ”现象。即在液体中产生气泡，气泡瞬间缩小到一个非常小的体积，在此过程中会发出瞬间闪光并伴随释放大量的热量。声致发光作为声学和光学的交叉学科引起了很多人的兴趣。本文对声致发光这种奇特的现象进行系统评述，讨论声致发光的几种机理，介绍单泡声致发光和多泡声致发光的研究进展以及各领域最新研究成果，并对声致发光未来的发展及应用前景作出展望。

Sonoluminescence is a phenomenon that when a liquid is subjected to a powerful sound wave, a “sound cavitation” is yielded in the liquid, which means a bubble is generated in the liquid and is instantaneously reduced to a very small volume, and an instant flash is produced with a large amount of heat released in the process. Sonoluminescence as an interdisciplinary subject between acoustics and optics has now attracted a lot of interest. This paper systematically reviews the peculiar phenomenon of sonoluminescence, discusses several mechanisms of sonoluminescence, introduces the research progress of single-bubble sonoluminescence and multi-bubble sonoluminescence and the latest research results in various fields, and proposes prospects for the future development and application of sonoluminescence.
