Perovskite light-emitting diodes (PeLEDs) with an external quantum efficiency exceeding 20% have been achieved in both green and red wavelengths 1 – 5 ; however, the performance of blue-emitting PeLEDs lags behind 6 , 7 . Ultrasmall CsPbBr 3 quantum dots are promising candidates with which to realiz...
