There are a lot of studies about nanocrystal of lead halide perovskites(LHPNCs) reported,which have received a widespread concern in photovoltaics and optoelectronics due to their excellent characteristics in high molar absorbance coefficient,high crystal defect tolerance,ultra-fast carrier mobility and their narrow full width at half maximum，even their excellent optoelectronic characteristics make them also attractive in sensing fields.In the past few years,many review articles have successively been published on the synthesis,stability improvement and applications of LHPNCs in solar cells,LEDs,lasers and catalysis,etc.However,reviews focusing on the sensing applications of LHPNCs,including an overview of LHP NCs in electrochemiluminescence(ECL),are still absent.The ECL studies and　applications of LHP NPs are summarized in this review.The remaining challenges and perspectives are discussed to promote the future development of LHP NPs related ECL studies.It is believed that this review will provide readers with the current status and future development of LHP NPs in the ECL studies.
