成像和测量纳米级的瞬态蒸汽泡由于其减小的尺寸和寿命，特别是在单粒子实验中，提出了一定的实验挑战。在这里，我们分析了三种技术，采用光学散射和声学检测在识别和量化个人光热诱导的蒸汽纳米气泡（NB）在很宽的激发能量范围。在光学透明介质中，最好的定量检测可以通过测量光学散射时间响应的持续时间来实现，而在不透明介质中，声学时间响应的幅度很好地描述了在没有应力波的情况下的NB。(C)2012年美国物理学会。[http：//dx.doi.org/10.1063/1.4772958]
Imaging and measuring transient vapor bubbles at nanoscale pose certain experimental challenges due to their reduced dimensions and lifetimes, especially in a single event experiment. Here, we analyze three techniques that employ optical scattering and acoustic detection in identifying and quantifying individual photothermally induced vapor nanobubbles (NBs) at a wide range of excitation energies. In optically transparent media, the best quantitative detection can be achieved by measuring the duration of the optical scattering time-response, while in an opaque media, the amplitude of the acoustic time-response well describes NBs in the absence of stress waves.
