Description of LED Fluorescent:
Fluorescent powder (Phosphors) are usually made from a suitable host material with an added activator. The best known type is a copper-activated zinc sulfide and the silver-activated zinc sulfide (zinc sulfide silver).
Festures of LED Fluorescent:
The host materials andoxynitrides,sulfides, selenides, halides or silicates of zinc, cadmium, manganese,aluminium, silicon, 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:how are the pigments in clothes differ from plant pigments?
- Pigments are pigments. They are made of molecules that absorb some colors and reflect others from the visible spectrum of light, which gives everything color. Black pigments absorb everything and reflect nothing, so black is the absence of color and it is why dark clothing are warmer in winter. White pigments reflect everything and absorb nothing, so clothing that is white is cooler in summer. Most plants have more chlorophyll, a green pigment, in them than other pigments, so the plant is overwhelmingly reflecting green back to our eyes and absorbing the red and blue ends of the spectrum. In fall, when the chlorophyll breaks down, we can see the yellow, orange, and red pigments that are also in the leaf for a few weeks. In this way, all pigments are alike. However, perhaps what your teacher is looking for is that the green pigment chlorophyll in plants not only absorbs red and blue wavelengths of light, it also uses that energy to excite electrons from the molecules of chlorophyll and send them through an electron transport chain that enables light energy to be converted to chemical energy and store it in the C-H bonds of glucose, which is made during photosynthesis. Other pigments, whether they be in clothes or other objects such as cars or just about anything else do not do this. Only plant chlorophyll, or the green pigment in plants, converts light energy to chemical energy. That is the one huge difference. Otherwise, like all other pigments, chlorophyll absorbs some wavelengths of light and reflects others, in the case of chlorophyll, green wavelengths of light.
- Q:Is gel food coloring a pigment or a dye?
- Dyes contain pigments, my friend. What is a pigment? They are like little beads. Very very tiny beads of the same color. Then if you spread these out, they give the thing a color. For example, the little green beads in leaves give it a green color. Pigment in our hair gives it a blonde/auburn/brown/black color. What is a dye? A dye is a liquid made up of water and pigments. The pigments are dissolved in water (well not really dissolve just that you cant see the beads) so that it's easier for us to use it. Everything that has a color is made up of pigments. So, gel food coloring is a thicker version of a dye that contains pigments.
- Q:hi:]i need the right order to apply skin pigments...
- Pigments are usually packaged in a finely milled loose powder form. After cleansing , toning and moisturizing,let the moisturizer absorb in the skin. Apply the skin pigments using a large compact powder brush/kabuki brush in a circular motion on face neck, then apply a second layer in a downward motion. Then use Evian water Mister to set the pigment. For eye pigments, put a thin layer of skin pigment first, then apply the eye pigment using a oval shaped dome brush
- Q:whats it for? lol
- itz for ur beautifing ur skin.
- 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:1.what is pigment2.what is it for ( whats its purpose?)3.what are other things people do with it
- Pigment is a loose powder that has highly concentrated color. They come in different finishes like matte or shimmery. You can use them as eye shadows and such, which is what most people do with them. They show up better and the metallic ones can be foiled (more vivid color and looks like metal almost) if you use them wet by putting a little bit of mixing medium or eye drops on your brush before dipping it in the pigment and applying it. They can also be used as lip colors by mixing with a clear lipgloss, or eyeliner if you use them wet or mix them with something like MAC's special eyeliner mixing medium. They also make a mascara mixing medium that can be used with pigments. Pigments really are a handy, universal product to have! Keep in mind that some pigments are not safe for use in the eye and/or lip area. If you look at MAC's website where the pigments are, you can check out the specifics about that under View Recommended Use. Also, if you use pigments wet, it's best to get a little bit of it in the jar lid, then dip the brush in it. That way you won't dampen and ruin the pigments in the jar, and moisture in the jar could promote the growth of bacteria.
- Q:Does anyone know its chemical formula or constituents ?
- Pigments are generally used for overdipping or decorating candles. Pigments do not fade and do not migrate/bleed, but pigments will clog wicks if used to color solid-colored candles. Pigment flakes are clean and easy to use and give vivid and brilliant colors. They are safe for the candlemaker and for the candlemaker’s customers. The pigment flakes comply with OSHA, TSCA and EN 071 (part 3) legislation. Pigments are insoluble in the medium they are coloring. Pigments, therefore, are not soluble in wax. They color the wax by dispersion. This means that pigments have to be distributed evenly throughout the wax, or dispersed in the wax, in order to color it (versus dyes which are soluble in wax and become a part of the wax to color it). Mixing, therefore, is very important. Usage and Dosage Instructions Dissolve pigments flakes in your wax formulation at approximately 185F - 85C. It is recommended to pre-disperse the required amount of color (see dosage chart) in a small amount of the dipping wax in a ratio of 1:5 color to wax. This should be done at 185F - 85C, using an electric mixer will disperse the color more quickly. Once the pigment is well dispersed, add it to the remaining dipping wax. Stir the dipping wax well before starting production and after each production break. Overdipping Dosage 2 dips : 1% by weight of wax formulation 1 dip : 1.5% by weight of wax formulation For color consistency, always add the same amount of color to your dipping wax. Use a scale to weigh the components of your dipping formulation. Always dip candles at the same temperature, temperature variations will result in color deviations. Too hot a dipping wax will make the shade of color on the candle appear lighter. Too cold a dipping wax will make the shade of color on the candle appear darker. Any variations in the overdipping wax used may result in a change of color on your finished candle. PROPER MIXING IS NECESSARY TO ACHIEVE UNIFORM DISPERSION OF PIGMENTS
- Q:What is better, Mac eye pigments or the regular eyeshadow? Also, has anyone tried the mixing medium solution?
- M.A.C pigments work really well. I have a few. And I haven't tried mixing medium solution.
- Q:hahahai have no clue what that means!
- It's a small plant that pigs love to eat. It's sort of like catnip, except that pigs love it (cats won't touch it). It is related to the catnip and mint family of plants.
