Abstract
To understand the light emission mechanism in single-bubble sonoluminescence experiment, the spectra are a key source of information. They already reveal that the light emission region is smaller than the bubble size. Theorists have been trying hard to predict the highest temperature and the size of light emission region. This is the main goal of my thesis work. According to the shock-wave theory, we analyzed the propagation of the shock wave. Then we take into account the van der Waals force and energy conservation to both analytically and numerically elucidate how the light emission region and its temperature distribution evolve. In the end, we are able to obtain the highest temperature intuitively and qualitatively.
