High color stability white OLED with an exterior sandwiched color conversion layer

Vacuum, 2019
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.

Localized surface plasmons enhanced color conversion efficiency in organic light-emitting device with surface color conversion layer

Synthetic Metals, 2015
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

BODIPY-based organic color conversion layers for WLEDs

open access: yesDyes and Pigments, 2020
Abstract The usage of organic dyes in phosphor conversion layer of WLED is an attractive approach since they have high molar extinction coefficient and photostability. Various types of organic pigments have been employed for this purpose such as BODIPY, perylene diimide, Rhodamine B, pyrene, Nile red, etc.
