Abstract: The acceleration ability of electrons in SiO2 and ZnS was compared through the variation of emission intensity based on ZnS: Er electroluminescence during the reverse of polarity of sinusoidal voltage. In order to avoid the influence of work function of electrode, cathodal and anodal materials were ITO (indium tin oxide). The ratio of maximum emission intensity under positive and negative half period is 2.18. This result demonstrates that the electron acceleration ability of SiO2 is 2.18 times stronger than that of ZnS.
