Lanthanide and Ladder-Structured Polysilsesquioxane Composites for Transparent Color Conversion Layers

open access: yesMaterials, 2023
Ladder-type polysilsesquioxanes (LPSQs) containing phenyl as a high refractive index unit and cyclic epoxy as a curable unit were found to be excellent candidates for a transparent color conversion layer for displays due to being miscible with organic solvents and amenable to transparent film formation.

Photonic Characterization and Modeling of Highly Efficient Color Conversion Layers With External Reflectors

open access: yesIEEE Photonics Journal, 2023
We propose a new method for fabricating arrays of colloidal quantum dots for color conversion layers (CCLs) with atomic layer deposited (ALD) encapsulation. Semiconductor processes were used to transfer the CCL onto a transparent glass substrate.

Investigation of high-performance perovskite nanocrystals for inkjet-printed color conversion layers with superior color purity [PDF]

open access: yesAPL Photonics, 2021
We synthesized cesium lead-halide perovskite colloidal nanocrystals using the hot injection method for wide-color-gamut low-cost displays. An efficient surface defect passivation technique was applied to further improve the optical performance of the green and red perovskite nanocrystals.
