Description of LED Fluorescent:

Many phosphors(Florescent Powder) tend to lose efficiency gradually by several mechanisms. The activators can undergo change of valence (usually oxidation), thecrystal lattice degrades, atoms – often the activators – diffuse through the material, the surface undergoes chemical reactions with the environment with consequent loss of efficiency or buildup of a layer absorbing either the exciting or the radiated energy, etc.


Festures of LED Fluorescent:

Phosphor layers provide most of the light produced by fluorescent lamps, and are also used to improve the balance of light produced by metal halide lamps. Various neon signs use phosphor layers to produce different colors of light. Electroluminescent displays found, for example, in aircraft instrument panels, use a phosphor layer to produce glare-free illumination or as numeric and graphic display devices. White LED lamps consist of a blue or ultra-violet emitter with a phosphor coating that emits at longer wavelengths, giving a full spectrum of visible light.

Q:what is pigment eyeshadow?
a mac pigment is a highly concentrated loose eyeshadow just a little will give u alot of color as opposed to a regular eyeshadow which isn't as vibrant or pigmented to give you a visual, you know when you put on eyeshadow, you have to apply it a few times to see some decent color? .. with mac pigments its so concentrated that in the first stroke you can see the colour as it is in the pot. you can even use it as eyeliner
Q:what is the pigment in hibiscus?
Hibiscus flowers bear pigments of three types: carotenoids, anthocyanins, and flavonols. The exact pigments (all three of those types are actually sizeable families of similar chemicals) and the exact proportions depend on the color of the particular flower: there are literally several hundred species in the genus Hibiscus, and they come in all shades of red, pink, yellow, and orange. Carotenoids are oil-soluble, fairly stable pigments that come in all shades of red, orange, and yellow. Anthocyanins are water-soluble and significantly less stable: they're responsible for the blues, pinks, purples, and reds, and in high concentrations can produce colors so dark as to look black. Flavonols are the least vivid of the pigments: they produce pale pastel yellows, cream colors, and off-whites. (Plain white flowers usually have no visible pigment at all.) Flavonols actually do most of their color absorption in the UV spectrum: they're the plant equivalent of the melanin in human skin, keeping them from getting sunburnt.
Q:MAC pigments Vs MAC eyeshadow???
pigments are loose powder i believe. i like the eyeshadows better. there's a much better selection of those anyway.
Q:Which of these is NOT a major photosynthetic pigment in plants?
Chlorophylls are greenish pigments which contain a porphyrin ring. This is a stable ring-shaped molecule around which electrons are free to migrate. Because the electrons move freely, the ring has the potential to gain or lose electrons easily, and thus the potential to provide energized electrons to other molecules. This is the fundamental process by which chlorophyll captures the energy of sunlight. There are several kinds of chlorophyll, the most important being chlorophyll a. This is the molecule which makes photosynthesis possible, by passing its energized electrons on to molecules which will manufacture sugars. All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll a. A second kind of chlorophyll is chlorophyll b, which occurs only in green algae and in the plants. A third form of chlorophyll which is common is (not surprisingly) called chlorophyll c, and is found only in the photosynthetic members of the Chromista as well as the dinoflagellates. The differences between the chlorophylls of these major groups was one of the first clues that they were not as closely related as previously thought. Carotenoids are usually red, orange, or yellow pigments, and include the familiar compound carotene, which gives carrots their color. These compounds are composed of two small six-carbon rings connected by a chain of carbon atoms. As a result, they do not dissolve in water, and must be attached to membranes within the cell. Carotenoids cannot transfer sunlight energy directly to the photosynthetic pathway, but must pass their absorbed energy to chlorophyll. For this reason, they are called accessory pigments. One very visible accessory pigment is fucoxanthin the brown pigment which colors kelps and other brown algae as well as the diatoms. From this I would say the answer is c.
Q:What is the importance of the accessory pigments?
Q:How many pigments does grass reflect?
Pigments are the colors that make grass look green. They are the pigments that do photosynthesis. Grass looks green because it reflects green light. It reflects the wavelengths of light that have the frequency of green light. Grass has other pigments that we do not see through the chlorophyll, but it is the light that is reflected.
Q:how to prepare coloured pigments?
Pigment does not might desire to do with pores and skin inevitably, a paint could be tinted with a pigment. curiously it is likewise a dry colorant, many times an insoluble powder. pores and skin colour is set by using the quantity of melanin in one's pores and skin, relative to ranges of exposure to the sunlight.
Q:What is the difference between primary and accessory pigments?
Color. Chlorophyll a is light green. The accessory pigments, chlorophyll b is olive green, the xanthophylls are yellow/brown, and the carotenes are red.
Q:pigments??
Photons are the packets of energy that light delivers. Different colors of light have different amounts of energy in each of the light's photons. So, green light's photons have different amounts of energy from red light's photons. Different materials absorb different amounts of energy via photons very selectively. It has to do with the energy states of the molecules, and the electrons that are in the outer shell.
