Fig. 4: Bright and energy-efficient QLEDs across the visible spectrum.
From: In situ n-doped nanocrystalline electron-injection-layer for general-lighting quantum-dot LEDs
Comparative analysis of our top-performing QLEDs against previously reported high-performing QLEDs in the orange-red (a), green-yellow (b), and blue-cyan (c) spectral windows, respectively. The x- and y-axis in each plot is the luminance at the corresponding Vp and at a 3 V bias. The peak EQE values are annotated next to each data point, with the respective reference numbers in parentheses. d Voltage-luminance characteristics of orange-red-, green- and blue-emitting QLEDs under intense electrical excitation. The shaded areas indicate the luminance levels required for different scenarios outlined to the right. Inset, current density-luminance-EQE characteristics under DC bias.
