WebJul 1, 2012 · The dye-based color filters have superior transmittance compared to the pigment-based one because dyes dissolved in the media have a smaller particle size, which leads to less light scattering [19]. Monophenylbenzoperylene 8 can make ideal transmittance spectra of red and green color filters when used as a yellow compensating dye, shown at ... A chromophore is the part of a molecule responsible for its color. The color that is seen by our eyes is the one not absorbed by the reflecting object within a certain wavelength spectrum of visible light. The chromophore is a region in the molecule where the energy difference between two separate molecular … See more Just like how two adjacent p-orbitals in a molecule will form a pi-bond, three or more adjacent p-orbitals in a molecule can form a conjugated pi-system. In a conjugated pi-system, electrons are able to capture certain photons as … See more An auxochrome is a functional group of atoms attached to the chromophore which modifies the ability of the chromophore to absorb light, … See more • Biological pigment • Chromatophore • Fluorophore • Litmus See more Halochromism occurs when a substance changes color as the pH changes. This is a property of pH indicators, whose molecular structure changes upon certain changes in the surrounding pH. This change in structure affects a chromophore in the pH indicator molecule. … See more • Causes of Color: physical mechanisms by which color is generated. • High Speed Nano-Sized Electronics May be Possible with Chromophores - Azonano.com See more
