| 摘 要： | 利用一种改进后的U型管圆锥泡声致发光装置,研究了乙二醇溶液中圆锥泡声致发光的发光光谱.实验结果表明,光谱为从紫外到可见光波长范围的连续谱,在589 nm附近叠加有钠的3p-3s原子发射谱线.在钠的原子发射谱线左侧测量得到了Na-Ar分子激发态跃迁形成的蓝卫星带,并首次在声致发光实验中测得了Na-Ar的红卫星带以及钠的3d-3p原子发射谱线.最后,讨论了钠的原子发射谱线以及卫星带的形成机理. |

| Abstract: | By using an improved conical bubble U tube, the spectra of conical bubble sonoluminescence in glycol are detected. Results show that the spectrum is continuum ranging from ultraviolet region to visible region, accompanied with the atomic spectral line owing to the 3p-3s transition of sodium around 589 nm. The blue satellite band of Na-Ar has been measured on the side of atomic spectral line; the red satellite band of Na-Ar and the 3d-3p atomic spectral line of Na are firstly measured in sonoluminescence. The mechanism of light emission of sodium and satellite are discussed. |
| Keywords: | conical bubble sonoluminescence spectrum red satellite band blue satellite band |
