Tuning the Color Temperature of White‐Light‐Emitting Electrochemical Cells by Laser‐Scanning Perovskite‐Nanocrystal Color Conversion Layers

ChemPlusChem, 2017
AbstractThe development of white‐light‐emitting electrochemical cells (LECs) has attracted great attention owing to their numerous advantages. Recently, perovskite materials have also shown many outstanding optoelectronic properties in light absorption and emission, and hence they are suitable for serving as the color conversion layers (CCLs) in solid ...

Effective Color Conversion of GaN-Based LEDs via Coated Phosphor Layers

IEEE Photonics Technology Letters, 2013
Gallium nitride (GaN)-based light-emitting diodes (LEDs) equipped with distributed Bragg reflectors (DBR) and covered with either red or green phosphor layers are fabricated to form quasi-monochromatic red or green light sources. Titanium oxide and silicon oxide layers are alternately deposited to form the DBR with high reflectivity of 94.6% at 450 nm ...

Structural design and optimization of quantum dot color conversion layers for AR microdisplays

Optics Letters
Augmented reality (AR) applications demand directionally high light conversion efficiency (LCE) from micro-LED quantum dot (QD) displays. We address this need by presenting a structural integration scheme that overcomes reabsorption loss and non-directional emission.

Optimization for white organic light-emitting diode based on DCJTB as color conversion layer

International Journal of Modern Physics B, 2018
In this paper, combining phosphorescence and fluorescence to form white light was realized based on DCJTB:PMMA/ITO/NPB/TCTA/FIrpic:TCTA/TPBi/Ir(ppy)3:TPBi/TPBi/Cs2CO3/Al. The effects of red fluorescence on this white light device was studied by adjusting the concentration of DCJTB.
