First, it is confirmed that the empirical equation B=B_0 exp (-C/√<V>) is applicable to the electroluminescent emission from ZnS (Cu, Al) EL phosphors embedded in a dielectric. Then, based on this equation, the frequency dependence of the electroluminescent emission is discussed in detail. The equation B_0 and C in the above equation are considered with respect to frequency and temperature. According to the experimental results obtained, the emission mechanisms of electroluminescence in this phosphor are considered, principally on the exciting high field, the primary electron source and the recombination process. Finally, it is concluded that primary electrons may be injected through the depletion layer by the tunnel effect and that the recombination process may act on the monomolecular law.
