Sonoluminescence as a probe of acoustic cavitation
Abstract
dc:descriptionSonoluminescence is defined as the light emitted when a liquid is irradiated with ultrasound. Sonoluminescence is observed during ultrasonic irradiation of chromium, iron, molybdenum, and tungsten carbonyl solutions. The observed spectral lines correspond to atomic emission from the metal atoms. The intensity of sonoluminescence from Cr(CO)$\sb6$ was studied as a function of dissolved gases to determine the effect of thermal conductivity and γ (C$\sb{\rm p}$/C$\sb{\rm v}$) on cavitational conditions. As predicted by thermal theories of sonoluminescence, the intensity of excited-state chromium emission decreases with increasing thermal conductivity of the noble gas, and the intensity of sonoluminescence from silicone oil solutions of Cr(CO)$\sb6$ was found to decrease with decreasing 1/(γ-1).
