Abstract

The universal luminescence behavior of three-level system is studied. Through theoretical analysis, the population of each energy level under different pump powers could be obtained. Further, the power decay rate coefficient (k_D) was proposed and analyzed. The k_D represents the effect of the excitation pump power on the decay process of S₂, and it is universal available either under weak or intense excitation powers. Besides, the population of S₂ could be described by the ratio of k_D to the total decay rate. The above analysis could be verified through the experiment.
