Abstract：With the development offlexible wearablesand self-driven sensors，triboelectrification-induced electroluminescence（TIEL）materials have atracted significant attention due to their unique mechanical-light energyconversion. Among them，doped zinc sulfide（ZnS）materials have become the hotspot due to their high luminescence eficiency，long lifetimeand tunable luminescence.This article reviews the recent progress of doped ZnS films on triboelectrification-induced electroluminescence in terms of working mechanism，performance optimization and practical applications.First，the luminescence mechanism of doped ZnS，the structure and working principle of doped ZnS films on triboelectrification-induced electroluminescenceare explained and introduced.Next，strategies in literatures are overviewed and commented on how to improve the luminescence intensity，and the progress of various application basedon this system in recent years is discussed.Finaly，we given anoutlook on thedevelopment trendand application prospectof doped ZnS films ontriboelectrification-induced electroluminescence.

1引言

ZnS作为一种典型的I-V族半导体，其电致发光现象早在20世纪中期已被发现，相对于发光二极管（Lightemittingdiode，LED）和有机发光二极管（Organic light-emittingdiode，OLED）等直流电驱动的载流子注人型发光器件来说，基于掺杂 zns 的交流电驱动的强场电致发光器件由于其高分辨率、良好的对比度、高亮度、长寿命、结构简单、柔性、可大面积均匀发光和可集成的优点而备受瞩目[2-4]。（剩余36630字）
