Abstract
Luminescence kinetics of nonthermalized electron‐hole plasma in highly excited CdS crystals with different concentration of native defects has been studied at T=298 K. The shape of the kinetics indicated an enhancement of the plasma nonradiative recombination with increased carrier effective temperature. The experimental results are in good agreement with a model of thermal activation of nonradiative capture by multiphonon emission in centers with the barrier energy of W=110 meV.Keywords
