Fluorescent powder or Phosphors are often transition metal compounds or rare earth compounds of various types. The most common uses of phosphors are in CRT(cathode ray tube) displays and fluorescent lights. CRT phosphors were standardized beginning around World War II and designated by the letter "P" followed by a number.Phosphorus, the chemical element named for its light-emitting behavior, emits light due tochemiluminescence, not phosphorescence.

- 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:I have dyed my hair dark brown for months now it keeps fading because i've had bleach on before hand, so I need some advice on buying decent hair dyes for pre-pigmenting it so my hair dye stops fading out into a horrible gingery brown!
- once you coloration your hair from blonde back to brown, you will possibly be able to desire to place the 'coloration' back into the hair as while that's bleached, that's stripped of coloration. hence you will possibly be able to desire to place the purple back into your hair. attempt making use of a mahogony coloration which has purple in it. this might forestall that green hue interior the hair. keep in mind, purple fades quicker than the different coloration so as quickly as the purple interior the colour starts to vanish seem boring, you are able to then use a typical brown in case you desire, or shop fresh while needed with the purple/brown. desire this enables.
- Q:I'm onto black-berry.. I wonder what else is available in 98362.
- Pigments from the past came from rocks, minerals, plants, and other natural materials. Those things are all still available. You can take classes at some universities that teach how to make your own paints, or dry pigments. For native American pigments, you have to research which tribe used which colors. To be totally authentic you could visit the tribe of your choice and see if you can learn from them. Sticking to your own zip code will not net you much, usually.
- Q:what is a pigment? Please describe it, and tell me the uses.?
- Pigments are a natural color in organisms. To understand pigments, you must understand the reflections of light. Pigments allows for organisms to have color, like the blue or brown in the eyes. For example, leaves in plants are color green because their pigments absorb all the colors because of photosynthesis except green and reflects off the color. Their plants are usually not green because they don't need to absorb light as much as the leaves does. Pigments depend on the type of light it absorbs. You are green in a dark room with green light right?
- Q:Please and thank you, it doesn't say so on the website.
- Mac Pigment Ingredients
- Q:I love the colours that pigments come in but I don't know how to use them. Is there any easy way?
- You can go to a store that sells makeup and ask them how to use it. They will even show you.
- Q:wut is the diff between those 2?
- MAC pigment is a loose eyeshadow that comes in a jar. It is made with ingredients that help adhere to the skin it is also easy to blend and doesn't cake. It is also to use pigment if you want very intense colors. And MAC eyeshadow well it comes in a little case it is in powder form it's a lot easier to apply than the pigment because the pigment tends to get all over the place. Personally I like the eyeshadow better more shades and easier to apply.
- Q:I hear about it cause my Friend is albino and she was born with no pigments in her hair,skin or eyes
- Melanin (i /?m?l?n?n/; Greek: μ?λα?, black) is a pigment that is ubiquitous in nature, being found in most organisms (spiders are one of the few groups in which it has not been detected). In animals melanin pigments are derivatives of the amino acid tyrosine. The most common form of biological melanin is eumelanin, a brown-black polymer of dihydroxyindole carboxylic acids, and their reduced forms. All melanins are derivatives of polyacetylene. The most common melanin – dopamelanin – is a mixed copolymer of polyacetylene, polyaniline, and polypyrrole. Another common form of melanin is pheomelanin, a red-brown polymer of benzothiazine units largely responsible for red hair and freckles. The presence of melanin in the archaea and bacteria kingdoms is an issue of ongoing debate among researchers in the field. The increased production of melanin in human skin is called melanogenesis. Production of melanin is stimulated by DNA damage induced by UVB-radiation,[1] and it leads to a delayed development of a tan. This melanogenesis-based tan takes more time to develop, but it is long lasting.[2] The photochemical properties of melanin make it an excellent photoprotectant. It absorbs harmful UV-radiation and transforms the energy into harmless heat through a process called ultrafast internal conversion. This property enables melanin to dissipate more than 99.9% of the absorbed UV radiation as heat[3] (see photoprotection). This prevents the indirect DNA damage that is responsible for the formation of malignant melanoma and other skin cancers. Albinism (from Latin albus, white; see extended etymology, also called achromia, achromasia, or achromatosis) is a congenital disorder characterized by the complete or partial absence of pigment in the skin, hair and eyes due to absence or defect of an enzyme involved in the production of melanin.
- Q:pretty self-explanatory...
- Pigments help in making food for the plants they also give color to it.Pigments are of different types which give different color to its leaves or fruits.Like mango is green first and then turns yellow coz green pigment is replaced by yellow pigment. Green pigment in most of the fruits is present only till it requires food and is raw.
- Q:How can you extract pure pigments from a sample of leaves in a form that you could test the absorbency of the various pigments??I don't know how to extract enough pigment in order to fill a cuvette and measure the absorbance, please help!! :D
- Separation of plant pigments using chromatography. Paper chromatography is a useful technique in the separation and identification of different plant pigments. In this technique, the mixture containing the pigments to be separated is first applied as a spot or a line to the paper about 1.5 cm from the bottom edge of the paper. The paper is then placed in a container with the tip of the paper touching the solvent. Solvent is absorbed by the chromatographic paper and moved up the paper by capillary action. As the solvent crosses the area containing plant pigment extract, the pigments dissolve in and move with the solvent. The solvent carries the dissolved pigments as it moves up the paper. The pigments are carried along at different rates because they are not equally soluble. Therefore, the less soluble pigments will move slower up the paper than the more soluble pigments. This is known as developing a chromatogram.
