摘要
拍摄了氯化铽(Tb Cl3)水溶液中不同实验参数条件下单泡和多泡声致发光的时间演化光谱。时间演化光谱(包括三价铽离子(Tb3+)线谱)表明了单泡和多泡声致发光的区别:单泡声致发光气泡具有氩气精馏的作用,而多泡声致发光气泡几乎不具有氩气精馏作用。随着声压的升高,Tb3+线谱相对连续谱越来越清晰,这表明SBSL气泡内外的质量交换率与声压幅度是正相关的。
The time-resolved spectra of single-bubble sonoluminescence(SBSL) and multi-bubble sonoluminescence(MBSL) in the terbium chloride(Tb Cl3) aqueous solution were collected for different experimental parameters. The spectra containing Tb3+ ions lines illuminated that comparisons between SBSL and MBSL: SBSL bubble can take several thousand sound cycles to rectify the argon though it is a weak rectification, and MBSL bubbles probably do not survive for more than a few cycles. The distinguish of Tb3+ ions lines attached the continuum spectra from SBSL increase with increasing sound pressure, which shows that the relation is positive between the rate of mass exchange of SBSL bubble and the amplitude of sound.
