By using the vapor-phase synthesis method, zinc sulfide single crystals were grown from pure zinc and a hydrogen sulfide bomb and they were doped with two impurities, copper and chlorine. The brightness waves of electroluminescence in these crystals were studied by applying rectangular pulse voltage. 8ince the E. L. of "in phase" was dominant in the crystals lacking chlorine and having appreciable voltage-dependency, it was concluded that it occurred as a result of the injection of electrons from the cathode. In order to classify the mechanism of E. L. of "out of phase," infrared quenching of E. L. was used. E. L. in ZnS: Cl, Cu was a typical case sensitive to the quenching, and E. L. in artificial junction (ZnS: Cl- ZnS:. Cu) was the typical case insensitive to the quenching. It was supposed that the difference between these two cases resulted from the difference in the mechanism supplying the primary electrons of E. L. (auth)
