摘      要：Perovskite based light-emitting diodes(PeLEDs)have become a powerful candidate for next-generation solid-state lightings and high-definition displays due to their high photoluminescence quantum yield(PLQY),tunable emission wavelength over the visible spectrum,and narrow emission *** the past few years,the development of red-and green-emissive PeLEDs has rapidly increased,and the corresponding external quantum efficiencies(EQE)have exceeded 20%.However,the research progress of blue-emitting PeLEDs is limited by its poor material quality and inappropriate device ***,the maximum EQE of blue PeLED is only 6.2%,which is far from the industrialization *** order to promote the development of blue PeLEDs,we summarize the recent research progress of blue perovskite materials and LEDs and discuss several fatal challenges,mainly embodied in low efficiency and poor *** order to overcome these challenges,detailed analysis and strategies are put forward in terms of the materials and *** the former,we summarize the feasible strategy for the preparation of efficient and stable blue-emissive perovskites using component *** the latter,we analyze the advantages and limitations of the different strategies for blue-emissive perovskite in *** the end of the review,a comprehensive outlook is detailed,including future development directions and several technical problems to be ***,we aim to highlight the significance and promote the industrialization of PeLEDs.
