| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Sonoluminescence spectrum from alkali-metal aqueous solutions contains continuum component and line emission from alkali-metal atoms. We measured sonoluminescence from argon-saturated 2M KCl solution at the frequencies of 28kHz , 48 kHz, 115 kHz, 325 kHz, 1MHz at various voltages. Frequency dependence of K-atom line intensity and width, and broad band spectra from 260 to 800 nm were investigated. Effect of ethanol on the line intensity and width was also studied at 115 kHz and 1 MHz. The K-atom line showed asymmetric broadening toward the red. The line width decreased with the frequency, and the intensity took maximum value at 115 kHz. Adding 1mM ethanol caused further line broadening at 115 kHz and no effect on line width at 1 MHz. Adding ethanol also caused quenching in K-atom line at both frequencies. These results indicated the K-atom emission occurs in gas phase inside bubbles and the line broadening is resulted from interaction of K atom with argon, water molecules or molecules decomposed from ethanol. The intensity of the continuum increased with the frequency, which suggested higher temperature at higher frequency. | |
