Progress of Doped ZnS Films on Triboelectrification-induced Electroluminescence

Abstract With the development of flexible wearables and self-driven sensors triboelectrification-induced electroluminescence (TIEL) materials have attracted significant attention due to their unique mechanical-light energy conversion.Among them doped zinc sulfide (ZnS) materials have become the hotspot due to their high luminescence efficiency long lifetime and tunable luminescence.This article reviews the recent progress of doped ZnS films on triboelectrification-induced electroluminescence in terms of working mechanism perfor mance optimization and practical applications.First the luminescence mechanism of doped ZnS the structure and working principle of doped ZnS films on triboelectrification-induced electroluminescence are explained and introduced.Next strategies in literatures are overviewed and commented on how to improve the luminescence intensity and the progress of various application based on this system in recent years is discussed .Finally we given an outlook on the development trend and application prospect of doped ZnS films on triboelectrification -in duced electroluminescence.
