Sonoluminescence| Sonoluminescence |
In General
* Idea: The emission of sharp
(~10−11 s) light pulses from air bubbles
(the presence of ∼1% Ar seems to be crucial) in water (works best) bombarded by
ultrasonic waves (at room p and T); The duration is 35–850
ps for various gases, and for all colors; The spectrum is featureless from 185
to 850 nm at least.
* Origin: 1997, Still unexplained,
possibly due to thermal Bremsstrahlung by electrons in the plasma created by the
shock wave from the collapsing bubble; 2000, Evidence for molecular excited states;
2003, Bremsstrahlung mixed with black body radiation; 2005, Plasma seen, T
up to 20,000 K.
* Applications: 1996, film
Chain Reaction with Keanu Reeves; 2002, Controversial claims that D atoms
fused to make T when gas bubbles in deuterated acetone collapsed to generate
temperatures of millions of degrees in `sonoluminescence' experiments; Timing
calibration of photmultipliers in SNO experiment.
