Abstract

We propose all-solution processed white quantum dots light emitting devices (WQLEDs) based on CdSe/ZnS Quantum dots(QDs)/polymer hybrid emissive layer which was red, green and blue (RGB) QDs and blue emitting homo-polymer blending. The proposed WQLED showed higher brightness, external current efficiency and color purity than only RGB blended WQLEDs. The maximum luminance was 11,600 cd/m2 and a maximum current efficiency was 1.29 cd/A at 7 V bias and exhibited the Commission Internationale de I`Enclairage (CIE) coordinates of (0.34, 0.36) near white light region.
