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: Can some one suggest chemical pigments that can be easily made from chemicals available in a chemistry lab for a project?I need the name of the pigment, reactants required and chemical equations of reactions involved.I need atleast 5 pigments
Typical pigments: carbon black (charcoal) titanium dioxide red iron oxide white lead cadmium red cadmium orange cadmium yellow
Q: why light and pigments are different?
A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which a material emits light. Many materials selectively absorb certain wavelengths of light. Materials that humans have chosen and developed for use as pigments usually have special properties that make them ideal for coloring other materials. A pigment must have a high tinting strength relative to the materials it colors. It must be stable in solid form at ambient temperatures. For industrial applications, as well as in the arts, permanence and stability are desirable properties. Pigments that are not permanent are called fugitive. Fugitive pigments fade over time, or with exposure to light, while some eventually blacken. Pigments are used for coloring paint, ink, plastic, fabric, cosmetics, food and other materials. Most pigments used in manufacturing and the visual arts are dry colourants, usually ground into a fine powder. This powder is added to a vehicle (or binder), a relatively neutral or colorless material that suspends the pigment and gives the paint its adhesion.
Q: does photosythesis requier pigment moulecuels?
Photosynthesis requires Chlorophyll, which is composed of a mixture of pigments like chlorophyll a, chlorophyll b and xanthophyll. These pigments allow certain wavelengths of light to be used for photolysis, a required stage of the photosynthetic process.
Q: ive been watching a lot of makeup videos on youtube and a lot of the girls use mac pigments. what exactly are they and how are they different from regular eyeshadow? are they easier or more difficult to use?
they are a loose powder like consistency, and they're just that.. they're super pigmented!!! ut i have about 26 pigments (: most are mac, some other brands.
Q: i bought the new neon pro pigments from mac , well 5 out of the six and i also bought 'basic red'i want to use these as eye shadows but i dont know howi also bought mac mixing medium for face and body but lol , i dont know how to use any of this stuffwhat can i do to use this stuff i mean will it turn out like regular eyeshadow if i use it right? will there be a shine to it? it will reduce fall out? should i put the mixing medium on my eye first , then let dry?do i need to possibly press the pigments in a pot with some kind of eye shadow liquid?i also bought the mascara mixing medium but want to know exactly what to do with thatand also , can i mix any of the pigments with lipgloss?http://cn1.kaboodle /hi/img/2/0/0/119/a/AAAAAlrx1LUAAAAAARmgiA.jpg

Q: pigment: its color (to our eyes) what color of light it absorbsChl a Chl bCartenoidsany right answers would bbe greatly appreicated thanks soo muchhh
pigment: .... reflected color to eyes .. what color of light it absorbs Chl a reflects green spectra between the blue and red absorption peaks. Some is absorbed at blue 450nm but most absorbed at red 680 - 700nm. Chl b reflects green spectra between the blue and red absorption peaks with a difference in which peak is stronger. Most is absorbed at blue 470 but also some at blue 430 and red 640 nm. Cartenoids reflect yellow, orange, or red and absorbs blue to blue-green light spectra. Xanthophyll absorbs well at 400-530 nm. Xanthophylls are a common sub class of the carotenoid pigment group. Beta-carotene absorbs most strongly between 400-500 nm.
Q: Can somebody answer this in AP BIO language please
A pigment molecule absorbs at specific wavelength(s), meaning that when light of a specific wavelength is incident to the molecule only certain wavelengths are absorbed while others are transmitted. The spectrophotometer emits monochromatic light (light of only one wavelength) which passes through the pigment molecule and a detector determines the amount of light that is either absorbed or transmitted by the sample. This is done at wavelengths from the UV (180-330 nm) to the visible (330-700 nm) and the light that is either transmitted or absorbed is detected by the spectrophotometer and is able to be graphed with absorbance representing the y-axis and wavelength representing the x-axis. The resultant graph will depict the absorption spectrum of that particular pigment molecule. Hope that helps.
Q: Many of the microorganisms found on environmental surfaces are pigmented. Of what possible advantage is the pigment?
Pigments have many advantages for the cell. They can absorb light to be used in photosynthesis. Specific pigments absorb light in a specific range - so the more pigments the more light can be absorbed and used for photosynthesis. Pigments also protect the cells from damage by UV radiation. More recently it has been suggested that some pigments inhibit the growth of some microorganisms.
Q: How are plant pigments involved in photosynthesis?
Plant pigments - as other pigments - interact with light to absorb only certain wavelengths. In plants the different sorts of pigments are useful to absorb available wavelengths of light and enable photosynthesis in shadow, in bright sunshine, in deep sea etc.: each pigment reacts with only a narrow range of the spectrum, there is usually a need to produce several kinds of pigments, each of a different color, to capture as much as possible of the sun's energy.
