From: Direct ambient photopatterning of RGB quantum dots for light-emitting diodes with EQE exceeding 20%
a Schematic device structure and energy band diagram of a representative QLEDs. b Comparison of the EL spectra of pristine (dashed) and crosslinked (solid) QLEDs. c−e Current density–voltage–luminance of pristine and crosslinked red-, green-, and blue-emitting QLEDs. f−h EQEs characteristics of pristine and crosslinked red, green, and blue QLEDs. Inset: EL images of pixelated red, green, and blue QLEDs. Scale bars, 10 μm.
