Abstract:    The transduction of sound into light through the implosion of a bubble of gas leads to a flash of light whose duration is delineated in picoseconds. Combined measurements of spectral irradiance, Mie scattering, and flash width (as determined by time-correlated single-photon counting) suggest that sonoluminescence from hydrogen and noble-gas bubbles is radiation from a blackbody with temperatures ranging from 6000 KH2 to 20,000  K  (He) and a surface of emission whose radius ranges from 0.1 μmHe to 0.4 μmXe. The state of matter that would admit photon–matter equilibrium under such conditions is a mystery.
