Untersuchurigen über das Leuchten implodierender Blasen in Flüssigkeiten (Modellversuche zur Sonolumineszenz
Thin-walled glass balls containing gas (gas pressure 0.7 torr to 35 torr) were imploded when immersed in paraffin oil or water. The radiation energy emitted during the implosion was measured as a function of the gas pressure for several gases (He, Ne, Ar, X, N2 and air). The spectrum of the light emitted was recorded for glass balls filled with xenon. The light emission can be interpreted as a consequence of the heating-up of the filling gas during the implosion. The emitted radiation energy is determined by the possibility of energetic excitation of the involved substances (filling gas, fluid and glass particles).
