Abstract This paper demonstrates localized surface plasmons (LSPs) enhanced color conversion efficiency in organic light-emitting device (OLED) with surface color conversion layer (SCCL). Ag nanoparticles (AgNps) deposited by thermal evaporation between substrate and SCCL were used for localized surface plasmons. The high-density, strong photons-LSPs

Journal of Physical Chemistry Letters, 2021
In micro-light-emitting diode (micro-LED) displays with color-conversion layers, a facile and efficient technology getting rid of the use of the color filters leads to a big technical leap in cost-effective fabrication. In this study, it is demonstrated that quantum dot (QD) color conversion layers can significantly suppress residual blue excitation ...

High color stability white OLED with an exterior sandwiched color conversion layer
Vacuum, 2019Abstract A sandwiched color conversion layer (CCL) was prepared on the exterior of a blue organic light-emitting diode (BOLED) to achieve white luminescence. Inorganic red aluminate phosphor was used for color conversion. To enhance optical outcoupling, light extraction layers (LELs) of microlens-like SiO2 scattering arrays (SO-LEL) and a roughed ...

Microfluidics-based quantum dot color conversion layers for full-color micro-LED display
Applied Physics Letters, 2021In this study, quantum dot color conversion layers (QDCCLs) for full-color micro-LED display were successfully fabricated using microfluidics to conduct red and green perovskite quantum dots to the position of the pixel array. The QDCCL with full-color pixel size of 200 × 200 μm and sub-pixel size of 140 × 50 μm was achieved.

Fabrication of hybrid white OLEDs with an inorganic color conversion layer
Molecular Crystals and Liquid Crystals, 2016ABSTRACTWe report hybrid white organic light-emitting diodes (WOLEDs) made by combining FIrpic-based blue-emitting OLEDs and a printable red-emitting inorganic phosphor. The color conversion can be easily controlled by adjusting the thickness of the red phosphor.
