- 論文の詳細を見る
An attempt at a qualitative understanding of the luminescence saturation mechanisms of ZnS: Cu, Al phosphor has been made by studying the exicitation current-density dependences of the luminescence efficiencies and decays at several activator concentrations, temperatures and accelerating voltages. The saturation behavior is independent of the Cu and Al concentrations in the region >10^<-4>g・atom/mol-ZnS. Neither the temperature nor the accelerating voltage affects the saturation. Nonradiative deactivation of the luminescent centers occursin the early stages of the decay. Auger recombination involving a donor-acceptor pair is postulated as the nonradiative process responsible for the saturation.
