Specifications of LED Fluorescent:
Phosphor thermometry is a temperature measurement approach that uses the temperature dependence of certain phosphors. For this, a phosphor coating is applied to a surface of interest and, usually, the decay time is the emission parameter that indicates temperature. Because the illumination and detection optics can be situated remotely, the method may be used for moving surfaces such as high speed motor surfaces. Also, phosphor may be applied to the end of an optical fiber as an optical analog of a thermocouple.

- 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: 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: Explain why plants need a variety of pigments to carry out photosynthesis?
- In photosynthesis plants make their which is a carbohydrate i.e. a compound of carbon, hydrogen and oxygen. That carbohydrate is glucose (C6H12O6). The chemical equation of photosynthesis is : 6CO2 + 12H2O = C6H12O6 + 6O2 + 6H2O Here water, carbon dioxide and light (light gives the energy to prform the reaction) helps to form chains of carbohydrate that further makes sucrose, a type of sugar, which can be utilized by plants as food.
- Q: I love the colours that pigments come in but I don't know how to use them. Is there any easy way?
- Pigments can be used the same way as your typical eyeshadows. Sponge applicators allow for a more vivid and intense colour pay off, while using a regular eyeshadow brush gives off a more sheer finish. Pigments can get messy, especially on your face. A good trick to remember is to dust a generous amount of translucent powder under the eye area before using pigments. This way if there is any powder fallout you will be able to sweep it all off without problems.
- Q: Explain light activation of pigments (absorption of light by pigments)?
- A pigment is a substance that imparts color by absorbing some frequencies of visible light but not others. For instance, there are a lot of substances that absorb ultraviolet light into the visible spectrum, in other words they also absorb plain violet light. Since they absorb violet light but reflect back the rest of light, they appear yellow. Purple pigments, on the other hand, are quite rare because they absorb purple light (which has the highest energy of visible light) and reflect back everything else. When anything absorbs a photon of electromagnetic radiation (light, x-rays, ultraviolet, infrared, microwaves, gamma rays, radio waves), it is activated which means that it takes the energy of the photon and goes to an energy state that is higher by the same amount of energy that was in the photon. At the molecular level, energy is quantized, meaning its restricted to particular states. For instance, vibrational energy corresponds to infrared light: there are only certain ways, called modes, that a molecule can vibrate in, if it can't vibrate in an appropriate mode, it can't absorb the infrared radiation that corresponds to being promoted to that mode. That's why substances can be transparent. At the higher energy state, the substance might be able to participate in chemical reactions that it would not be able to participate in in a lower state. That's usually what is meant by light activation. So a pigment that absorbs visible or UV light might become activated and react with something or react in ways that it wouldn't be able to in the dark.
- 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 was thinking of this all day long and then i thought of posting this question for you to help me sort it out
- Pigments are molecules that absorb specific wavelengths (energies) of light and reflect all others. Pigments are colored: the color we see is the net effect of all the light reflecting back at us. Absorb: Electrons in molecules can exist at specific energy levels. Normally they exist at the lowest possible energy level they can. However, if enough energy comes along to boost them into the next level, they can absorb that energy and occupy that higher level. This is what pigments do. The light they absorb contains' just the right amount' of energy necessary to push them into the next level. Any light that does not have enough or has too much energy can not be absorbed and is reflected. The electron in the higher energy level, however, does not 'want' to stay there(i.e. it is unstable). It 'wants' to return to its normal lower energy level. In order to do this it must get rid or release the energy that has put it into the higher energy state to begin with. This can happen several different ways: 1) The extra energy can be converted into molecular motion and lost as heat. 2) Some of the extra energy can be lost as heat energy, while the rest is lost as light. This re-emission of light energy is called florescence. 3)The energy, but not the e- itself, can be passed onto another molecule. This is called resonance. 4)The energy and the e- can be transferred to another molecule. Plant pigments usually utilize the last two of these reactions to convert the sun's energy into their own. When chlorophyll is isolated from the enzymes it is associated with, the second scenario can be seen to happen.
- Q: what is pigment?
- a pigment has some kinds like biological pigment and arsenic pigment. i dont know much about the arsenic pigment. i would just tell something about the biological pigment. in biology, pigment is any material resulting in color of plants or animals cells. many biological structures like eyes,fur,hair and skin contains pigments like melanin in specialized cells called chromatophores.
- Q: a. chlorophyll ab. chlorophyll bc. chlorophyll cd. carotenoid pigments
- Chlorophylls are greenish pigments which contain a porphyrin ring. This is a stable ring-shaped molecule around which electrons are free to migrate. Because the electrons move freely, the ring has the potential to gain or lose electrons easily, and thus the potential to provide energized electrons to other molecules. This is the fundamental process by which chlorophyll captures the energy of sunlight. 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. From this I would say the answer is c.
