Spectral and kinetic properties of electroluminescence of ZnS:Cu powder in polymer structure
Spectral and kinetic measurements of the light output have been made for AC electroluminescent structure. ZnS:Cu is luminescence active layer in the structure. In kinetic measurements, excitation was by rectangular wave voltage pulse of 1 ms duration. During the excitation the structure emits blue-green light. The maximum of the spectrum lies at about 455 nm.
