WebCyanines, also referred to as tetramethylindo (di)-carbocyanines [1] are a synthetic dye family belonging to the polymethine group. Although the name derives etymologically from terms for shades of blue, the cyanine family covers the … Fluorescence shifts energy in the incident illumination from shorter wavelengths to longer (such as blue to yellow) and thus can make the fluorescent color appear brighter (more saturated) than it could possibly be by reflection alone. Rules. There are several general rules that deal with fluorescence. See more Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower See more Mechanism Fluorescence occurs when an excited molecule, atom, or nanostructure, relaxes to a lower energy … See more There are many natural compounds that exhibit fluorescence, and they have a number of applications. Some deep-sea animals, such as the greeneye, have fluorescent structures. See more Lighting The common fluorescent lamp relies on fluorescence. Inside the glass tube is a partial vacuum and … See more An early observation of fluorescence was described in 1560 by Bernardino de Sahagún and in 1565 by Nicolás Monardes in the See more There are several general rules that deal with fluorescence. Each of the following rules has exceptions but they are useful guidelines for understanding fluorescence (these rules do not … See more In August 2024 researchers reported the creation of the brightest fluorescent solid optical materials so far by enabling the transfer of properties of highly fluorescent dyes via spatial and electronic isolation of the dyes by mixing cationic dyes with anion-binding See more

WebElectroluminescence is the result of radiative recombination of electrons & holes in a material, usually a semiconductor.The excited electrons release their energy as photons - light. Prior to recombination, electrons and holes may be separated either by doping the material to form a p-n junction (in semiconductor electroluminescent devices such as … WebUV tattoos or blacklight tattoos are tattoos made with dyes that fluoresce visibly under a blacklight or other ultraviolet light source, similar to fluorescein or rhodamine.Depending upon the ink used a UV tattoo can be nearly invisible when illuminated only by light within the visible spectrum. Therefore, they have found popularity with people seeking a subtler … canadian tire skil table saw

The color defined as blue in the RGB color model, X11 blue, is shown at right. This color is the brightest possible blue that can be reproduced on a computer screen, and is the color named blue in X11. It is one of the three primary colors used in the RGB color space, along with red and green. The three additive primaries in the RGB color system are the three colors of light chosen such as to provide the maximum gamut of colors that are capable of being represented on a computer or tele… Web2,000-year-old ceiling reliefs uncovered during restoration work at Egypt's Temple of Esna, also known as the Temple of Khnum.
