High brightness thin film electroluminescent devices with ZnS: Tb active layer were prepared by high frequency sputtering method. The impact cross section of Tb
3+
was calculated by measuring the decay time
quantum efficiency and the dependence of the two emisson spectrum intensities ratio on applied voltage. The hot electron distribution of ZnS: Tb was studied and compared with that of ZnS: Mn to find out the probable reason of the difference of their efficiency.
