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: A.catalyzes chemical reactions.B.absorbs light.C.transports materials.D nverts energy to light.E s energy.
pigment is the coloring of your skin and considering your skin gets darker under sunlight im going to say it absorbs light.
Q: I always hear about pigments from MAC and Loreal, etc. and I am confused about what exactly they are.So can someone please THOROUGHLY explain what they are and what they can be used for?
Pigment okorder Pigments can be used for many different cosmetic purposes. eyeshadow blushes added to a clear gloss you make a brand new lip gloss added to clear nail polish base. a hilight color, added to body spray for shimmer added to gel for a tinted gel the list goes on and on. i hope this helps!
Q: explain an absorption spectrum of different pigments and the action spectrum ofphotosynthesis.
A pigment is any substance that absorbs light. The color of the pigment comes from the wavelengths of light reflected (in other words, those not absorbed). Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects to be detected by our eyes. Black pigments absorb all of the wavelengths that strike them. White pigments/lighter colors reflect all or almost all of the energy striking them. Pigments have their own characteristic absorption spectra. The action spectrum of photosynthesis is the relative effectiveness of different wavelengths of light at generating electrons. If a pigment absorbs light energy, one of three things will occur. Energy is dissipated as heat. The energy may be emitted immediately as a longer wavelength, a phenomenon known as fluorescence. Energy may trigger a chemical reaction, as in photosynthesis. Chlorophyll only triggers a chemical reaction when it is associated with proteins embedded in a membrane (as in a chloroplast) The familiar colors of the rainbow in the spectrum include all those colors that can be produced by visible light of a single wavelength only, the pure spectral or monochromatic colors.
Q: What are accesory pigments and why are they important?
Accessory pigments, also called, Photosynthetic Pigments or Chloroplast pigments, are pigments which are present within the cell of a Chloroplast used to harvest a greater spectrum of light.y are colored compounds which absorb and transfer light energy to chlorophyll. Pigments are light-absorbing molecules. In addition to chlorophyll,other pigments, principally yellow and orange carotenoids, as well asother forms of chlorophyll, are also present in green plants. These molecules absorb light and then pass the energy to the chlorophyll and accessory pigments, like the carotenoids, enable the plants to use more ofthe light than is trapped by chlorophyll alone.
Q: what is the relationship between chlorophyll a, accessory pigment?
Chlorophyll is the pigment that allows plants—including algae—to convert sunlight into organic compounds in the process of photosynthesis. Chlorophyll a is the predominant type found in algae and cyanobacteria (blue-green algae), and its abundance is a good indicator of the amount of algae present in the waters of the Chesapeake Bay. Excessive quantities of chlorophyll a can indicate the presence of algae blooms. These usually consist of a single species of algae, typically a species undesirable for fish and other predators to consume. Unconsumed algae sink to the bottom and decay, using up the oxygen required by other plants and benthic organisms to survive. The presence of too many nutrients, such as nitrogen and phosphorus, can stimulate algal blooms and result in reduced water clarity. Chlorophyll a also plays a direct role in reducing the amount of light avalable to plants in shallow-water habitats. This directly impacts the ability of underwater bay grasses to thrive. Like their terretrial cousins, grasses need sunlight to grow. As chlorophyll a levels increase, the amount of sunlight reaching underwater grasses declines. Chlorophyll a is the main pigment, chlorophyll b and carotenoids are accessory pigments. accessory pigments help broaden the absorbtion spectrum, as chlorophyll a absorbs violet-blue and red light. with the addition of accessory pigments chlorophyll b and carotenoids, yellow-green (chlor b) and violet and blue-green light (caro)
Q: are photosynthetic pigments separated based on their polarity or based on their molecular structure?Thanks
Molecular structure... Chlorophylls are greenish pigments which contain a porphyrin ring. This is a stable ring-shaped molecule around which electrons are free to migrate. 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.
