NO2分子电子激发态荧光辐射寿命的测定
Measurement of the radiative fluorescence lifetimes of electronic excited states of NO2
摘要
利用激光诱导荧光技术,实验测定了NO2分子513～520 nm范围内AA～U22B2电子激发态6个不同振转能级激光诱导荧光衰减寿命,研究了激发态荧光寿命与气压和激发波长的关系,得到了无碰撞衰减寿命和碰撞猝灭系数,并对其反常长寿命进行了讨论.
Abstract
In this paper, the radiative fluorescence lifetimes of electronic excited states of NO2 were measured at six different excitation wavelength in the region of 513～520 nm. The dependence of the fluorescence lifetime on gas pressure and excited wavelength were also studied. By using the Stern-Volmer mechanism, the collision-free radiative lifetimes and collisional quenching rate constants were obtaind. The apparently anomalously long lifetime of NO2 was discussed with the perturbation theory.
