Abstract
Several papers dealing with the mechanism of ZnS:Mn2+ emission in TFEL devices have been reported and two principal phenomena which govern the decay of the yellow Mn2+ emission have been registered [ 1,2,3 ] :
-
Diffusion mechanism and energy trapping : an excited Mn* transfers its energy via non excited Mn to killers that reduces the emitted light by the introduction of non radiative channels.
-
Interaction between excited Mn* : This phenomena occurs only at high excitation level ; the higher the excitation level, the lower the decay time.
