Figure 5

Characterization of perovskite LEDs based on CsPb(Br1-xClx)3 films, , 0.35, 0.40, 0.45, and 0.50: (a) normalized EL spectra; (b) current density and luminance versus voltage; (c) EQE versus current density; (d) corresponding CIE coordinates. The peak EQE and maximum luminance of LEDs are also presented.
