Convolutional Color Constancy [PDF]

open access: yes, 2015
Color constancy is the problem of inferring the color of the light that illuminated a scene, usually so that the illumination color can be removed. Because this problem is underconstrained, it is often solved by modeling the statistical regularities of ...

Wide color gamut LCD with a quantum dot backlight

open access: yesOptics Express, 2013
We analyze the color performance and system efficiency of three commonly employed liquid crystal display modes with a blue LED-pumped red and green quantum dots (QDs) backlight. Based on the measured QD emission spectra, we can achieve 115% color gamut in CIE 1931 and 140% in CIE 1976 color space, while keeping the same energy efficiency as ...

Tellurophene‐Induced Triplet–Singlet Spin‐Flip Acceleration: An Advanced Design for Narrowband Organoboron Emitters with Fast Reverse Intersystem Crossing

open access: yesAngewandte Chemie, EarlyView.
Linking an auxiliary dibenzo[b,d]tellurophene unit markedly accelerates exciton spin conversion in multi‐resonance‐type thermally activated delayed fluorescence emitters. Owing to the heavy‐atom effect of tellurium, the corresponding OLEDs retain remarkably high external electroluminescence quantum efficiencies exceeding 25% even at an exceptionally ...

Yarn Formation Mechanism and Application of Rotor Spinning Wide-Color Gamut-Blended Yarn for Ostwald Color Solid

open access: yesJournal of Natural Fibers
By applying the Ostwald color solid in spinning, we investigated how to correlate the Ostwald color solid with spinning process parameters and achieve the wide-color gamut-blended yarn spinning, based on rotor spinning principles.

Establishing a Model Precursor System: Over a Decade of Research on Carbon Dots from the Citric Acid‐Urea System

open access: yesAdvanced Functional Materials, EarlyView.
The citric acid/urea (CA‐Urea) precursor system offers a versatile, scalable route to carbon dots with tunable luminescence and multifunctionality. Mechanistic insights into precursor chemistry and reaction parameters have enabled doping, surface modification, and hybridization strategies, yielding CDs for luminescent devices, sensing, catalysis ...

Triple Matrix Confinement‐Induced Ultrabright Afterglow From Carbon Dots With Multivariate Responsive Afterglow Colors for Advanced Dynamic Information Encryption

open access: yesAngewandte Chemie, EarlyView.
A novel carbon dots material (BUL‐CDs) with an initial afterglow brightness (406 cd m−2) far exceeding that of other afterglow luminescent materials was developed. Furthermore, the BUL‐CDs exhibited time‐dependent afterglow colors, excitation‐dependent afterglow colors, and thermochromic afterglow in response to triplet variables.
