The sketch of experimental setup. To reduce the error of measurement from the space instability of the bubble, the entrance slit of the streak camera was adjusted to 50 nm, near the narrowest possible.
The summed streak image and the shape of the SL pulses in SA. (a) The integrated streak image. (b) The histogram of (a) where the solid line is the best-fit Gaussian distribution. The inset in (b) shows the shape of SL flash in water (Ref. 11 ). The concentration of the SA solution used is 85% by weight. The bubble is driven by 1.40 Pa at .
The FWHMs of the SL pulses in 85% SA by weight under different driving pressures. The inset shows the FWHMs in water (Ref. 11 ).
The rise-time and fall-time of the SL pulse as functions of the driving pressure. The host liquid was the SA solution dissolved by argon gas.
The FWHMs of the SBSL pulses in SA solutions with different concentrations. All solutions have been dissolved with argon gas.
The ambient radii of the bubbles levitated in experimental SA solutions.
Skewness of photon distribution of SBSL under different driving pressures in SA solutions with different concentrations.
