Effect of copper doping on the lifetime of the upper 5T2 laser level of the iron ion in ZnSe
摘要
The effect of copper doping of ZnSe:Fe crystals on the kinetics of luminescence of iron ions is investigated in this work. It has been discovered that doping with copper leads to a sharp decrease in the radiative recombination of iron ions at a temperature of 77 K. The obtained results are explained based on the model of nonradiative relaxation of iron ions due to Auger recombination with the participation of electrons in the conduction band.
