摘要：

Time-correlated single-photon counting reveals that the width of flashes of sonoluminescence ranges from under 40 to over 350 ps for mixtures of various gases in water. Flash widths and emission times are independent of wavelength from the ultraviolet to the infrared. These measurements suggest that sonoluminescence originates in a plasma which quenches as its temperature drops below the ionization potential. For helium bubbles this model implies peak temperatures greater than or similar to 20 eV. [S0031-9007(97)05155-7].
