If the liquid has been degassed and is irradiated with a standing acoustic wave, a single bubble sonoluminescence (SBSL) can be generated. To study of SBSL, some emission detecting devices were set up. A Photo multiplier tube (PMT) successfully detected SBSL emission. However, Time response of PMT was too slow to observe emission hysteresis of SBSL. For observe SBSL emission spectroscopy and emission hysteresis, some relations between emission and cycle of acoustic wave will be clearly.
