Abstract
s Metal-halide perovskite nanocrystals have attracted great scientific attention in the field of light-emitting diode (LED) due to their excellent optical and electrical properties such as narrow emission linewidth, photoluminescence quantum yield approaching unity, high charge carrier mobility, and halogen anion composition-dependent tunable bandgap. Over the last few years, considerable progress has been achieved on red and green perovskite LEDs (external quantum efficiencies exceeding 20%), however, the performance of blue LEDs still lags far behind that of red and green counterparts. In this review, overall background of perovskite nanocrystal and research progress of perovskite nanocrystal-based blue LEDs are summarized.
