The ZnS phosphors are suspended with tricresyl phosphate between two transparent conducting glass plates. Tricresyl phosphors are slightly conductive. Some ZnS phosphors in tricresyl phosphate excited by superimposing a variable direct bias on a constant alternating voltage showed abnormal electroluminescent effects. Even when the d.c. bias was cut off, brightness of E.L. changed with time and this condition continued for a long time. There were some differences in the brightness of the electrode polarity of d.c. bias superimposed on a.c. voltage. The negative polarity side was brighter than the positive. This phenomenon was different from the delayed light emission shown by Zalm. In this paper we report mainly about the brightness of the light waves of the abnormal E.L. emission and summarize the results of the experiment.
