Ru原子荧光及其寿命的测量

FLUORESCENCE AND LIFETIME MEASUREMENT FOR Rul

本文设计了一个荧光探测系统,采用了电热原子化激光共振激发的方法,可方便地对难熔金属的原子荧光寿命进行测量,从而确定原子能级的寿命,实验中测得Ru原子\4d^05s(~6D)5pl^7P_4~0能级的寿命为70.4ns(±5％)。

A fluorescence detection system is described in this paper. By means of thermal atomization and laser resonance excitation technique, the system can measure the lifetimes of atomic fluorescence of refractory metals and therefore the lifetimes of the atomic energy levels. The measured lifetime of Rul energy level [4d65s(6D)5p]7P_4~0 is 70.4(±5%)ns.
