Color of Copper/Copper Oxide

چکیده
Stochastic inhomogeneous oxidation is an inherent characteristic of copper (Cu), often hindering color tuning and bandgap engineering oxides. Coherent control the interface between metal oxide remains unresolved. propagation front in single-crystal Cu thin film demonstrated to achieve a full-color spectrum for by precisely controlling its oxide-layer thickness. Grain-boundary-free atomically flat films prepared atomic-sputtering epitaxy allow tailoring layer with abrupt via heat treatment suppressed temperature gradient. Color nearly red/green/blue indices realized precise thickness; samples cover ?50.4% standard space. The copper/copper reconstruction quantitative yield from “pigment” (complex dielectric functions Cu2O) light-layer interference (reflectance spectra obtained Fresnel equations) produce structural color. Furthermore, laser-oxide lithography micrometer-scale linewidth depth through local phase transformation oxides embedded metal, providing spacing necessary semiconducting transport optoelectronics functionality.

A Study of Relationship Between Color Inconstancy Level and CIELAB Color Coordinates
In commercial point of view, it is of great interest to find colors with high color constancy level. Color constancy as a relatively property of object’s appearance could be affected by different factors. In this article, the color inconstancy index of CMCCON02 and CIELAB color coordinate of 1269 samples of Munsell at CIELchº color system to study any correlations, was calculated. The correspon...
متن کاملPreparation of Cobalt Oxide/Zinc Oxide Nanocomposite
Cobalt Oxide/ Zinc Oxide nanocomposite was synthesized by dropwise addition ofCo(NO)3.6H2O and Zn(NO3)2.4H2O solutions to KOH solution at different temperatures followed bycalcination at 300ºC for 4 h. The morphology and structure of nanoparticles and the influence oftemperature on particle size were studied using scanning electron microscopy (SEM) and X-RayDiffraction (XRD). Minimum particle s...
متن کاملPreference of Broiler Chickens for Feed Color
Studying broiler preference to feed color is important for improving comfort and welfare of broilers and it may be beneficial for improving performance. The aim of the first experiment was to examine day-old chick's preference in different light colors to different feed colors. One hundred and sixty Ross 308 newly hatched broilers, never exposed to feed, were allocated into pens illuminated ...
متن کاملColor imaging via nearest neighbor hole coupling in plasmonic color filters integrated onto a complementary metal-oxide semiconductor image sensor.
State-of-the-art CMOS imagers are composed of very small pixels, so it is critical for plasmonic imaging to understand the optical response of finite-size hole arrays and their coupling efficiency to CMOS image sensor pixels. Here, we demonstrate that the transmission spectra of finite-size hole arrays can be accurately described by only accounting for up to the second nearest-neighbor scatteri...
متن کاملThe Use of Fundamental Color Stimulus to Improve the Performance of Artificial Neural Network Color Match Prediction Systems
In the present investigation attempts were made for the first time to use the fundamental color stimulus as the input for a fixed optimized neural network match prediction system. Four sets of data having different origins (i.e. different substrate, different colorant sets and different dyeing procedures) were used to train and test the performance of the network. The results showed that th...
