How does the glow gang shine, and how does the glow stick shine twice

The chemicals in glowsticks are mainly composed of three substances: peroxides, esters, and fluorescent dyes. To put it simply, the principle of glow stick luminescence is that peroxides and esters react, and the energy after the reaction is transferred to the fluorescent dye, which then fluoresces.

A glass tube interlayer is usually placed in the glow stick on the market, and the inside and outside of the interlayer are isolated from peroxides and ester compounds, and after rubbing, the two compounds react to make the fluorescent dye glow.

Supplementary Q&A Burning rods, usually with oxygen in them, use sodium, magnesium, potassium and other metals to send oxygen to these metals to make them react, then they can be burned in water, and at the same time, these active metals reflect hydrogen in the water, ignite hydrogen, and release a lot of heat at the same time.

The torch of the Sydney Olympics was carried underwater using strong reducing substances such as sodium and potassium.

There's a battery in it, and after the latch is unplugged, just turn on the switch, but it won't light up for a long time.

One"Phosphors"Luminous revelations.

In order to understand the chemical composition of phosphor, we first thought of the luminescence of glowworms, and the luminescence principle of glowworms mainly includes the following series of processes.

Photoproteins Photogenic enzymes contain oxygenated photoproteins (emit green light).

Oxygenated photoproteins H2O photoproteins.

This is the reason why glowworms can continue to emit light, and the light flashes and flashes, it is worth noting that the green light emitted by glowworms is a kind of"Cold light"The result is a 97% conversion rate.

Secondly, we also pay attention to the luminescence of luminescent plastics, which are mainly mixed with some radioactive substances in ordinary plastics, such as 14C, 35SR, 90SR and Na, Th and luminescent materials ZNS, CAS, these sulfides are excited and emit visible light (cold light) under the irradiation of radioactive light.

The chemical composition of phosphors is deepened from vague silicate and tungstate, single elements BA and SR to the standard chemical formula, and its chemical composition is:

Category: Chemical Formula.

Color density.

Red Pink Y2O3: EU White.

Green Pink CEMGL11O19: TB White.

Blue Pink Bamgal10O17: EU White.

Bimodal Blue Pink Bamga10O17: (EU, MN) White.

The composition of the upconversion phosphor, that is, the infrared excitation phosphor, is:

Chemical Composition: YeryBF3

Appearance: white inorganic powder.

Grain size: 30 nm

Excitation wavelength: 980nm

Glowing color: green.

Characteristics: high light transmittance, high solvent resistance, acid and alkali resistance.

Several ways to deal with phosphor hazards.

When mercury vapor reaches 3 mg, it can cause chronic poisoning within 2 to 3 months; Acute mercury poisoning can be induced at milligram levels, and if the amount reaches 20 milligrams, it will directly lead to the death of animals.

Once mercury enters the human body, it can quickly diffuse and accumulate into tissues and organs such as kidneys and chests, chronic mercury poisoning can lead to mental disorders, autonomic disorders, acute symptoms often headache, fatigue, fever, redness, swelling and soreness of the gums in the oral cavity and digestive tract, rotten bleeding, loose teeth, etc., some ** red spots, papules, a small number of kidney damage, individual kidney pain, chest pain, dyspnea, cyanosis and other acute interstitial pneumonia.

If mercury is not properly stored and disposed of, it will also cause great harm to the ecological environment, it enters the environment in various forms, directly pollutes soil, air and water, and then enters the human body through the food chain, endangering people's healthy life, so it must not be discarded everywhere.

If the indoor fluorescent tube is broken, 1 gram of iodine can be added to alcohol and then fumigated or directly dispersed on the ground with 1 gram of cubic meter of iodine for 8 12 hours, so that the volatilized or sublimated iodine and mercury in the air generate involuntary mercury iodide (hg+i2 hgi2). To reduce the concentration of mercury vapor, contaminated floors can also be rinsed with 5% 10% ferric chloride or 10% bleach.

Summary. Pro, the glow stick is a chemiluminescent item, and its luminescence principle is to release energy through internal chemical reactions, thereby emitting fluorescence.

If you want to make the fluorescent tomato stick glow a second time, you can try the following methods:1Heat the glow stick with hot water to restart the chemical reaction inside it, creating a glowing effect.

2.Expose the glow stick to the sun for a while to allow it to absorb enough light, then place it in a dark place and you can see it glow again. 3.

Refrigerate the glow stick in the refrigerator for a while, then take it out and rub it in, which activates the chemical reaction inside it and makes it glow again.

Bend the glow stick slightly, break the glass tube in the plastic tube, and gently shake it so that the two liquids are well mixed to glow. The shape of the glow stick is mostly strip-shaped, with a built-in glass tube interlayer, and the liquid inside and outside the laminated layer is bent, hitted, rubbed, etc., so that the glass is broken, causing the reaction of two internal compounds to cause the fluorescent dye to glow.

The liquid inside and outside the laminated glass tube of the glow stick glass tube is peroxide and ester compounds, which will react and produce energy to make the fluorescent dye shine.

Light sticks can be used in entertainment, night fishing, weddings, outdoor, military, engineering construction, underwater operations, concerts, etc.

The luminous time of the glow stick can range from 30 seconds to 48 hours, and the length of the luminous time is inversely proportional to the ambient temperature, which is non-toxic and harmless.

Put the glow stick in a low temperature environment (such as refrigerator, freezer) to inhibit the chemical reaction of the two liquids in the light stick, and you can continue to use it after taking it out.

The glow time of the glow stick can range from 30 seconds to 48 hours. The length of the glow stick glow time is inversely proportional to the ambient temperature (i.e., the higher the ambient temperature, the shorter the glow time of the glow stick) and inversely proportional to the initial brightness of the glow stick (i.e

The higher the brightness of the glow stick when it is just folded, the shorter the light emitting time).

Hello dear, it is a pleasure to serve you! If you want the glowstick to shine continuously for a second time, you can use it as follows:1

Freeze the glow stick in the refrigerator for a period of time, and then take it out quietly and shake it, which can prolong the glow time. 2.Heating a glow stick in hot water and then taking it out and shaking it can accelerate the chemical reaction, making it glow brighter and longer-lasting.

3.Placing the glow stick under a UV lamp can stimulate its fluorescent color and enhance the luminescence effect. It should be noted that the glow stick has not been used once, and it should be disposed of correctly after use, and should not be discarded at will, so as not to affect the environment.

Glowsticks use some special intermediates of chemical reactions to emit light, and once the reaction is over, other substances are generated, which cannot or are difficult to turn into the original reaction substances. If you want to make the glow stick bright for a longer time, you can put the used glow stick in the refrigerator to freeze, and when we want to use it, you can take out the light stick with warm water to scald it slightly, remember not to use the water temperature too high, otherwise the use time of the light stick will be shortened, this method can increase the brightness of the light stick, to meet the requirements you want to use. Because the glow stick is chemiluminescent, it needs to be within a certain temperature to have a chemical reaction, put it in the refrigerator to freeze, the temperature is low, it stops the reaction, and it does not glow.

Take it out of the refrigerator and scald it with warm water, it reaches a certain temperature again, reacts again, and continues to glow. The glow stick glow has a lot to do with the temperature, the higher the temperature, the greater the brightness, but the shorter the time, the fire wolf glow stick is more popular in China, and domestic David TV, cultural media companies have cooperation.

Very professional products, very insightful, as long as you want to get the solution can be done.

Mine is a stick stick glow stick.

The silver light stick like an ordinary bracelet can be placed in the refrigerator and frozen, and it will continue to fluoresce when you hit it on a hard object, I don't know which one you are.
