应用激光诱导荧光方法研究K_2漫射带产生的机制

On the machanism of K_2 diffusion band produced by LIF

通过比较在氩离子激光器两个较短波长(457.9nm和476.5nm)作用下K_2所产生的荧光光谱,讨论K_2漫射带产生的另一种可能的机制,说明钾分子的三重激发态在某种情况下也可作为能量的存贮状态。

Comparing the LIF spectrum produced by light beams at two wavelengths 457.9 and 476.5nm of Ar+ laser, we suggest a new possible mechanism for generating K2 diffusion band and show that tho excited triplet states of K2 can also be used as an energy reservoir under certain conditions.
