Abstract
Time-resolved studies of pulsed dc electroluminescence from ZnS:Mn, Cu-powder phosphors are reported. Emission bands from the orange Mn2+transition and a very broad band extending from 1.5 to 3.6 eV are detected. The broad band, attributed to higher conduction band transitions of hot electrons, is used as a probe of avalanching in the devices. Study of the onset of the Mn2+luminescence provides evidence for direct impact excitation of Mn2+ions. Current densities much higher than expected for uniform current flow are deduced from the rate of increase of luminescence rise transients.Keywords
