Sonoluminescence spectra from Ar-saturated KC1 solutions were measured at the frequencies of 147.9 kHz and 1.029 MHz in the temperature range of 15-40℃. Spectra of K atom emission showed that the spectral lines at 147.9 kHz were broadened asymmetrically to the red side, but the line width at 1.029 MHz was narrower than that at 147.9 kHz. To examine the effect of water vapor, the temperature of solution was changed in the range from 15 to 40℃. The result indicated that the spectral shape was hardly dependent on amount of water vapor and final temperature in collapsing bubbles. Effects of dissolve gas were also studied. The results for Xe-saturated solution suggested that the spectrum indicated two components, unshifted narrow line, and shifted broadened line. The spectral line of K atom emission from He-saturated solution was broadened symmetrically. These results were consistent with the results of spectroscopy in gas phase.
