Abstract：Perovskite quantum dotlight-emiting diodes（Pe-QLEDs） have shown immense application potential in displayand lighting fieldsdueto their narrow full-width at half maximum（FWHM）and high photoluminescence quantum yield（PLQY）.Despite significant advancements in their performance，challenges such as defects and ion migrationstillhindertheirlong-termstabilityandoperational eficiency.Toaddresstheseissues，variousoptimizationstrategies，including ligandengineering，interface passivation，andself-assembly strategy，are beingactively researched.This review focuses on thesynthesis methods，challenges andoptimization of perovskitequantum dots， which are critical forthecommercializationandlarge-scale production of high-performanceand stablePe-QLEDs.
