Description of LED Fluorescent:

In these applications, the phosphor is directly added to the plastic used to mold the toys, or mixed with a binder for use as paints. ZnS:Cu phosphor is used in glow-in-the-dark cosmetic creams frequently used for Halloween make-ups. Generally, the persistence of the phosphor increases as the wavelength increases. 


Festures of LED Fluorescent:

The host materials   andoxynitrides,sulfidesselenideshalides or silicates of zinccadmiummanganese,aluminiumsilicon, or various rare earth metals. The activators prolong the emission time (afterglow). In turn, other materials (such asnickel) can be used to quench the afterglow and shorten the decay part of the phosphor emission characteristics.

Q:whats pigment?
n biology, a pigment or biochrome[citation needed] is any material resulting in color of plant or animal cells, which is the result of selective color absorption. Many biological structures, such as skin, eyes, fur and hair contain pigments (such as melanin) in specialized cells called chromatophores. Plant pigments include a variety of different kinds of molecules, including porphyrins, carotenoids, and anthocyanins. Chlorophyll is the primary pigment in plants; it is a porphyrin that absorbs red and blue wavelengths of light while reflecting green. Carotenoids are red, orange, or yellow tetraterpenoids. Anthocyanins (literally flower blue) are water-soluble flavonoid pigments that appear red to blue, according to pH. They occur in all tissues of higher plants, providing color in leaves, stems, roots, flowers, and fruits, though not always in sufficient quantities to be noticeable.Betalains are red or yellow pigments. Like anthocyanins they are water-soluble, but unlike anthocyanins they are indole-derived compounds synthesized from tyrosine. For more info visit : en.wikipedia.org/wiki/Biological_...
Q:what is one reason why plants have accessory pigment molecules like chlorophyll b and carotenoids?
Pigments in plant biology are actually (as you may know) long-chain conjugated systems which absorb light at specific frequencies. This specificity is largely due to the morphological and physical features of each pigment molecule. Since Chlorophyll a only absorbs well at wavelengths of about 400-450 nm and 650-700 nm a plant empowered with only this photosynthetic molecule would have an extremely limited range of spectral absorption. This is where the accessory pigments come in. Chlorophyll b's absorption peaks at 450-500 nm and 600-650 nm and Xanthophyll's at around 400-530 nm, allowing for a much wider absorption range. Carotenes contribute to photosynthesis by transmitting the light energy they absorb from chlorophyll back into the energetic system. None of the pigments, absorb well in the green-yellow region which is largely responsible for the abundance of greens we see throughout nature. The five main pigments are: Chlorophyll a - a blue-green pigment Chlorophyll b - a yellow-green pigment Carotene - an orange pigment Xanthophyll - a yellow pigment Phaeophytin a - a gray-brown pigment Phaeophytin b - a yellow-brown pigment A good illustration of this concept can be found in this graph of Photosynthetically Active Radiation, illustrating the absorption peaks of all the molecules: upload.wikimedia.org/wikipedia/co...
Q:what is pigment dispersion syndrome?
Pigment dispersion syndrome (PDS) is an affliction of the eye that, if left untreated, can lead a form of glaucoma known as pigmentary glaucoma. It takes place when pigment cells slough off from the back of the iris and float around in the aqueous humor. This is not what causes problems; however, if the pigment flakes clog the trabecular meshwork, preventing the liquids in the eye from draining, pressure can build up inside the eye. This pressure can cause permanent damage to the optic nerve. This condition is rare, but occurs most often in Caucasians, particularly men, and the age of onset is relatively low: mid 20s to 40s. Most sufferers are nearsighted. There is no cure as of yet, but PDS can be managed with eye drops or treated with simple surgeries. If caught early and treated, chances of glaucoma are greatly reduced. Sufferers are often advised not to engage in high-impact sports such as long-distance running or martial arts, as strong impacts can cause more pigment cells to slough off
Q:How do you make paint pigments?
There are distinct forms of eyeshadows, that means distinct finishes. Matte, for instance, shall be very, very focused within the colour, wherein as a lustre will exhibit up sheer, and you can barley get any precise pigment out of it. MAC paint is for a base, or primer to your eye lids, that means you might placed that on BEFORE you place any eye liner, shadow, pigment, and so on. Depending at the colour paint you utilize, it would increase or tone down and eye shadow or pigment then you definitely situation at the lid. Pigment is an excessively, very focused free powder. You best want a tiny, tiny pinch of it, and the boxes they arrive in, move a verrrry good distance. The intent individuals mostly use pigments as a shadow replacement, might be for the reason that both MAC does now not bring the precise colour of the paticular pigment in a shadow, or they are utilising it to increase shadows, or finally, they are blending it with shadows to create distinct colours. Hope this is helping.
Q:What pigments are used in photosynthesis?
Chlorophyll(green) is the primary pigment used in photosynthesis. Besides chlorophyll, plants also use pigments such as carotenes(orange) and xanthophylls(yellow).
Q:Why does a plant use several pigments instead of one or two?Why are plant leaves green?
The several other pigments that are found with chlorophyll a multi-task. They work with chlorophyll a to provide energy by absorbing light from the sun and other jobs as well. Some accessory pigments help protect the plant while collecting energy, others help regulate the photosynthetic process.
Q:what are three main families of pigments in plants?
Q:What is pigment?????
