Electrical field-dependent characteristics of perovskite MQW LEDs. a Normalized EL and PL spectra of the device under various bias voltages. EL (2.5 V, black square, 1.6 V, red circle), PL (0.75 V, blue triangle, −2 V, magenta triangle). b Dependence of current density on the driving voltage under various illumination intensities. c Time-resolved PL decay transients of perovskite films under various bias voltages, measured at 780 nm
